Not so sure I agree with this. Plenty of tech from modern CPUs relies on microcode from the BIOS, so it’s pretty important that this is kept up to date. e.g. my own B550 mobo has had a stack of bugs that AMD have fixed over the last 12 months. You don’t need to install every single beta BIOS that’s released, but I would certainly stay current with the production ones, no less than I would keep my GPU drivers up to date.
As it happens, modern motherboards are pretty hard to brick with a BIOS update. I happen to have a TUF board myself, and they are dead easy - download the update file onto a USB stick, reboot to BIOS and install. One note about the TUF boards (at least mine, anyway) - you should always save your configuration as a “profile” before applying a BIOS update as they always (at least with mine, anyway) wipe the config back to default after an update. This is no problem as it boots back to the BIOS after the update, so you just load back the settings from the saved profile, reboot and you are good to go again.
