It's cool they issued a new BIOS. I have an extremely similar (but older, I think -- it is the first gen of boards that support EFI) Gigabyte motherboard, and the community hacked in support for M.2 boot (with a PCIe adapter passthrough board) maybe 5 years ago.
I only looked into this because I had to upgrade the video card (NVidia's drivers go obsolete way before the hardware), and the new video card wouldn't post without a new BIOS. Gigabyte had issed one even though the motherboard was ten years old. I thought about going the NVME route, but didn't bother. The video card higher priority.
I even ran stable diffusion on a machine like that one, but a few years newer (with a covid-era video card).
