Since Proxmox maintains their own version of lxc, they should be able to import the patch. They are building lxc from trixie though. So I doubt we'll get 6.0.5, I could be wrong though...
I was working with the Incus project owner on their forums and it looks like this is a regression in 6.0.4 which was fixed in 6.0.5.
I'm going to open a bug report with Proxmox.

This is what I did to install them: apt install pve-headers nvidia-driver
Debian driver on PVE 9.x...
