[flashrom] Schematic: MSI X570-A PRO (MS-7C37) ?

[Clay Daniels]

Looking for schematic for:
MSI X570-A PRO (MS-7C37)

Ivan Ivanov pointed out a very nice detailed view which I could not find in
MSI marketing propaganda, and it looks like I will need to use a CH341A
external programmer. This means I need to know if the vcc to the chip is
3.3v or 5v. I have no real clues without a schematic. Are these available?

See nice Russian NIX picture at:
