I recently got an asrock x470 taichi motherboard. It boots into windows normally but when I try to get into the bios by pressing f2/del it gives me the post code Ab but I cant see the bios on my display. There is no enter bios screen while I am booting. When I use the restart to UEFI program it does the same thing as if I were to press f2/del. Can anyone help me fix my issue?

You can try clearing CMOS.

Another thing I would strongly vouch against - try updating or just reflashing BIOS via the Windows utility. That's scarry stuf, though.

Did you try Windows 10 advanved restart options, which also allow for reboot to UEFI?

UEFI/BIOS settings are unavailable.
