B550 Pro4 w/ P3.40 BIOS

Evening all.

I believe I've found a bug with the BIOS with regards to NVME drives.

If I reformat the NVME drives to 4K sectors, the BIOS will fail to list them as bootable drives when I press F11.

When I put back 512B format for these drives, the BIOS successfully finds and lists them after I press F1 on boot.

I have upgraded the BIOS to P3.40 and the issue still persists.

I prefer 4K sectors as they're more efficient and I run virtual machines.

Any ideas or does this bug needs fixing?

These NVME drives will be used as the OS boot drives. They're:
