Updating the BIOS on a Supermicro board

I’ve recently bought hardware for a new NAS server build. Some of that is still in the throes of shipping (postal services have been pretty unreliable as of late), but most of it has arrived: A Supermicro mainboard, case, M.2 SSD and a PSU allows me to get started on the build. As I like to live dangerously, I also upgraded the BIOS on the mainboard1. Since the process was somewhat involved, I’m documenting it here....
