Request: Restore CSM support on the ASRock X570M Pro4.

After updating the BIOS to 2.80, the CSM functions are forcibly disabled in the UEFI.
This creates 2 problems:
1. When I use low solutions, the screen is always zoomed in (despite that I set the monitor to center the image)
2. I am unable to boot via BIOS.
Can someone try mod it to get CSM back? I also want full menu unlock if possible, since they do removed lots of options.
My CPU is an AMD R7 4750G and I am using the iGPU.
