Hi, I was pretty sure the card has EFI support because I had it running in a different passthrough setup (Intel GPU and this GTX) and it worked.
Your advice and the comments from the folks at https://www.reddit.com/r/VFIO/ got me in the right direction. The GTX was tainted by the kernel because I was booting with CSM (AKA legacy boot) enabled in the UEFI of the mainboard. It took me three days to figure that out. Thanks to the community! P.
