Not really, BIOS is old and it doesn't know anything about OPAL drives.
I don't know about UEFI machines but I suspect not many know about
SEDs/OPAL either.

On the other hand, you don't know what kind of treatment the BIOS would
do to the password before sending it to the SED, one bios could send it
plaintext, others could send key scancodes, you don't want to get
anywhere near that kind of nonsense. This would mean that you might not
be able to unlock the disk if you move it to another machine.
