I mean the system bios, whether you are using legacy or EFI mode is largely
irrelevant.

You can blacklist the amdgpu driver so it doesn't load and then dump the dmesg
output. E.g., append the following to your kernel command line in grub:
modprobe.blacklist=amdgpu
If you want to load it manually after the system has booted just run (as root):
modprobe amdgpu
