Flash Updating BIOS

[Prolicity]

I'm helping my friend build a PC today, and two of his parts include the B550M Pro-VDH WIFI motherboard and a Ryzen 5 5600 CPU. It's possible they're not compatible yet so I have a flash drive prepared to flash update the BIOS. Should I immediately flash update it with just the motherboard before we start building or should I help him build it to see if it works already and if it doesn't then flash the BIOS with everything installed?

I'd just build it and flash it when everything is done.   You need BIOS version 7C95v2A or later for the 5600 to work.

What @Hinjima said.
Build a minimum system outside the case and see if it works first.
