I haven’t updated my BIOS (unintentionally)

Hello, I’m unsure if this is the right subreddit to ask for this kind of advice for, but I recently discovered that my BIOS is on version F4 (From 2021), while the latest version that’s out is F15b (Forgot the date but I think last year?).

I’m not very knowledgeable with PCs (I was unaware that updating BIOS was something I needed to do manually), and looking it up on the internet hasn’t helped as much as I’d like.

Some sources tell me that I absolutely should update it and some sources tell me that if my system is running fine (which it is) then there’s no need. Reddit has rarely ever let me down so I’m hoping I could get some advice. (If this is the wrong subreddit for this type of question, I’d appreciate a point in the right direction) Thank you!
