In Opera, the unique ID remains until whenever you decide to flush its
local data. From a prior submission of mine regarding Opera's ID ...
Are you using the app-specified pseudo-VPN incorporated into Opera?
That is when the device ID gets used (when connecting to SurfEasy VPN
server, owned by Opera).
You can clear the device ID: Opera menu -> More tools -> Clear
browsing data -> Third party services data. A new ID gets created when
you next connect to their VPN server. There may be extensions that
include purging the third party data when they purge Opera's other local
data. The unique/device ID is sent in the encrypted traffic only when
connecting to Opera's SurfEasy VPN server.

"For the VPN in Opera Browser for Desktop, we create a subscriber ID
(generated in sequential order across all subscribers) that allows us to
manage that user on our system. If that user clears their browser
cache/history, they’re assigned a new generated subscriber ID."
Since the traffic is encrypted, you won't be able to read it when
intercepting the web traffic from that web browser using a local proxy
(e.g., Wireshark). The ID sticks in Opera until you clear it. When you
next use their VPN, a new ID gets creates and sticks thereafter. You
can clear it as often as you want. Check if there is an extension that
clears it upon exit from the web browser so it will be new in every web
session of the web browser (*if* you use their VPN service).
As for Epic, you would have to see what options it has for clearing its
local data. I thought Epic's intent was to be a [more] secure Chromium
based web browser, so it doesn't support extensions since those can
share or steal data.

Why does Epic block almost all Addons or Extensions?
"... Epic only allows a few trusted Addons."
Didn't see any listed at
https://epicbrowser.com/webstore/. Maybe the
only addons that Epic supports have already been pre-installed into the
product.
The Epic author's site has a dearth of information about his product.
Although some pages have a top banner advertising the availability of
the VPN fetaure, there is no further information: nothing about when it
gets used, how to enable/disable it, if it is a true VPN or just an
anonymizing proxy to hide your IP address, if it is implemented solely
at the client (which means it isn't a VPN) or connects to their server
and what is that server, etc. Guess the author equates hiding
information as a security measure.
There is the Epic forums where you could ask other Epic users how that
product works, if they know.
http://forum.epicbrowser.com/
By searching there on "vpn", I saw a user saying they were queried as to
which country to use a proxy. So it looks like Epic uses scattered
servers to achieve its claimed VPN feature. However, there is still no
informtion if Epic is running those proxy servers or if they're from
some public list of public proxies. If they are public proxies (because
the Epic author cannot afford the cost of all those resources for a free
product that has no advertising or tracking) then all Epic's "VPN" does
is anonymizing. You don't need Epic, Opera, or any particular web
browser to configure them to use a public proxy to hide your IP address.

So a banner at their site claims Epic has a VPN feature (which works
only if provided as a service at some server) and yet the admin in their
forum says it is just a proxy, not a VPN server.
Opera has a feature that it will use their server to submit queries to
the online search engines. This would hide your IP address from the
search provider. Well, either the search engine provider gets to track
your searches or Opera can. The privacy risk is not mitigated: you
either trust the search provider to not abuse the tracking information
or you trust Opera with the same information. I disabled that feature
in Opera when I trialed the product but still saw search queries going
to their proxy server. I found a config file that dictated the
resulting destination for various search engines. Don't remember which
ones were left behind but any queries to those search engines sites
still had Opera sending the queries through Opera's proxy server.

EVERY web browser can be configured to use a free public (or free
private) or paid proxy server. Do a search on "free public proxy" and
you find lots of them; however, the free ones are not reliable nor are
they fast (and even the fastest proxy will still add delay as it is
another hop in the route but also has to deconstruct and rebuild the
traffic so it looks like it originated from only that server).
https://www.google.com/search?q=free%20public%20proxy
Note that there are blacklists of public proxy servers. There are
blacklists of the private/paid proxies, too. That's how sites can block
you from connecting to them. They may not want someone visiting that is
deliberately attempting to thwart their regional restrictions on content
access or other reasons they want to restrict access based on IP pools.
