    I wish to test a custom OVMF build from Gerd Hoffmann's repo.

    Repo has cutting-edge firmware builds at:
    Since Windows 7 is still said to have the best KVM/Spice/Agent driver support I wish to test specifically his build of OVMF with CSM enabled. I believe this may make Windows 7 guest VMs boot with UEFI and GPU passthrough which has been been a major headache for anyone who has tried - and possibly impossible without this version of OVMF with CSM enabled.

    Can I install his repo along side PVE's implementation and pass an argument -bios /path/to/OVMF-with-csm.fd

    since the repos are rpm base, i do not think you can just install them
    what you could do, is to extract the firmware files, and either replace ours (which would have to be done every update of our package) or
    use the 'args' parameter of a vm config to include your own efi file commandline argument with a custom path
