I’ve read this is the preferred way to flash a BIOS on an MSI X570S, X570 or B550 board.

I have an MSI X570S Unify-X Max.

This is what I’ll use. Good plan?

This is the method I have seen on the web with the most success in this AMD motherboard generation, due to most of them using WSON soldered spi.
