How do I manually check for BIOS security updates from my motherboard manufacturer? (programming.dev)

I read somewhere on Reddit that people who use Linux should periodically, manually check for security updates to their computers' BIOS from their motherboard manufacturers, because Linux apparently ends automatic updates once you leave Windows. I have no idea of where to look on the ASUS website for my Zenbook 14, or if that's even the right place. Could anyone give any guidance on this matter? Is this a thing that we should indeed be doing semiannually or something?

And what else should I be doing on a schedule (even if annually), while I'm at it? Haha.

Edit: thanks, everyone!

Asus seems to be supported by fwupd, at least they are listed on the vendors list, so I suppose (?) it can manage the update for you. Depending on your distro this might event be automatic by default, otherwise depending on your DE this might be available from the graphical software store or just from the cli.

They are supported, but they only push updates to a few models (typically server models).

For desktop motherboards, its better to go to ASUS's support website, look up your board, download the latest BIOS, and install it per their instructions.

Also, if you have ANY custom settings in your BIOS, such as overclocked CPU, mem timings, IOMMU enabled, SecureBoot keys, etc, BE SURE TO BACK THEM UP before upgrading your BIOS. I have a notes.txt file of all my BIOS settings because I have to reapply everything after an update since it sets everything to default.
