> GPU sharing with docker and VMs

This should work without needing a reboot. You do have to bind the vfio driver at boot, but the archwiki gives a script to unbind vfio and load the Nvidia driver: https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF#Bi...

Which anecdotally worked fine on my RTX3050.

I did give up as well though, all of this is just too much of a faff. Hopefully Intel continues to make strides with their discrete graphics. They are the only manufacturer without DRM blocking this feature which the hardware can obviously do.
