I have a VFIO VM host, and the hosts GPU is in slot 2, with slot 2 set as the primary display in the UEFI. This works in the UEFI configuration, which properly starts up on the slot 2 card, but as soon as the boot loader starts up it will switch to the GPU in slot 1 if there is a display attached. Is there a way to blacklist a specific display device, or force the order that it looks for displays?
