Configuration Files, Nested Virtualization

[my kay]

So I have been trying to enable nested virtualization so that I can run Virtualbox in a Windows HVM, but I am running into issues. I was trying to follow the instructions from the Xen wiki, as well as this https://groups.google.com/g/qubes-devel/c/UzO0BsIfIow/m/C7us11XHAwAJ post, but I am new to Qubes so I didn't realize that it no longer uses individual config files for AppVMs. I found this https://groups.google.com/g/qubes-users/c/K8lfxC8xdp4/m/jGwC-gxnBAAJ thread, and am now trying to create a custom config file in /etc/qubes/templates/libvirt/xen/by-name based off of the default xen.xml file, but I am not sure how to edit the file in a way that would allow nested virtualization in my windows vm.

A somewhat more recent thread:

Editing config files would be the easy part; I think you'd have to
recompile Qubes to enable nested virtualization. I used to run
Virtualbox on Windows as well, but instead converted my workflows/VMs
over to Qubes only. Do you have a specific use case that requires
Virtualbox?
