I assume you're not familiar with mac or didn't read the while bug history.
Mac are booted using the EFI runtime one of the successors to BIOS.

You're wrong here. The bios is there if you boot in 'legacy mode'.
Legacy mode means your EFI machine will load and run a (slow) BIOS emulation.

This exact step happens in legacy mode.
If you boot in native EFI you don't have any BIOS at all.

As nice as it sounds 'fixing' would imply writing a separate
KMS driver which would work entirely without the need to access the BIOS.
