I just updated my TUF Z690 WIFI D4 to 1201 too and it seems to have a few more options regarding CPU VCORE. After some tweaking it seems I can now achieve the same overclock with slightly less voltage too.
Version 1201 has the same errors as the bios version 1003 with the Ram OC with the G.Skill F4-4000C14D-32GTRS and XMP. Ram clock maximum 2993-3200 MHZ, otherwise Safe Boot error. Version 901 works correctly with 4000MHZ CL14.
