@poddingue Yeah, that does make sense. I understand that this wouldn't necessarily be an intended usecase. I'll probably just get a cheap consumer GPU. And apologies for if this question is painfully obvious, but how would I mention @Team-Hypervisor-Kernel?
But if I can hypothesize, firmware is usually accessible via sysfs, there's an Archlinux guide here: https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface/Secure_Boot#Determine_OpROM_signature for determining OpROM signatures, which includes getting it as a file, so maybe that could be loaded in someway, but I know not of the feasibility of that.
