Bios flash with laptop?

[wk_online_]

EDIT: the BIOS was fine and had nothing to do with the CPU, the issues lied elsewhere

 

I’m in the middle of building a PC for/with my friend. We have concluded that we cannot get an output to the monitor because the Ryzen 5600X is too new for the BIOS on the ASUS PRIME B550M-A WIFI. The problem is is that it would take annoyingly long to obtain an older Ryzen chip, so we were wondering if there is any way to force a BIOS flash using a laptop connected via Ethernet. Also this motherboard doesn’t have a BIOS flash button which is where the issue lies. The bios is on version 3404. Will I be able to use a laptop to force flash the BIOS, or do we just need an older CPU to update the BIOS? If you need anymore info just ask!

Nope, the 5600X has worked way before BIOS 3404:

 

That's not the issue.
