It seems this can be done via setterm command. It might require kernel
or kernel command line parameter changes depending on what you need to
do.
This link may be of some help:

I have a Debain (Armbian) server that does not boot to any form of
window manager, so what is seen on the screen is just the command console.
What I would like to do is have the console screen go into screen power
save mode after some period and recover when keyboard or mouse are used.
Is there a simple way to configure that?

What I would like to do is have the console screen go into screen power
save mode after some period and recover when keyboard or mouse are used.
Is there a simple way to configure that?

There are also Linux Console Private CSI Sequences

documented in man 4 console_codes that include:
ESC [ 9 ; n ] Set screen blank timeout to n minutes.
ESC [ 13 ] Unblank the screen.
ESC [ 14 ; n ] Set the VESA powerdown interval in minutes.
So, for example, I added \e[9;16] to the beginning of /etc/issue
when it became apparent that Linux wasn't blanking the console
any more. I think it was buster, but could have been stretch.
I wouldn't notice if bullseye still doesn't. Don't quote me on
the version.
Cheers,
David.
