In general, you shouldn’t need to update your BIOS that often. Installing (or “flashing”) a new BIOS is more dangerous than updating a simple Windows program, and if something goes wrong during the process, you could end up bricking your computer.
What is the point of updating BIOS?

How do I know if I need to update my BIOS?
Some will check if an update is available, others will just show you the current firmware version of your present BIOS. In that case, you can go to the downloads and support page for your motherboard model and see if a firmware update file that’s newer than your currently installed one is available.
