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!

Search for your specific model, it may or may not be this link, but for a Zenbook 14 this came up after searching "ASUS Zenbook 14 support".

You'll need to format a flash drive and save the BIOS update to it, then boot into BIOS and run the update. For many laptops, instead of saving a BIOS update to the drive you may need to run a setup tool (usually a .exe, so may need compatibility tool) and boot to the USB.

As for frequency, just periodically check the notes for the BIOS releases and determine whether to update based on the features or patches in it. Not necessary to update for everyone one, and many security updates will be more for servers than general purpose personal computers, but that's up to your own risk analysis.
