Note to self and other people interested.

Maybe “loader.efi: Do not use as frame buffer BLT-only GOPs“ https://cgit.freebsd.org/src/commit/?id=76cbf786406311b7d89db0b725f9cd0c890e54e4 is worth trying, going to check this out tonight (CET)

This is disabled as far as I know, as all SATA/NVMe storage is available. At first I thought this might be due to the intel i9-11900T video not supported yet, but also with a GeForce GT 710 installed the video doesn’t work in UEFI mode.
