I use excel function everday . So when I use F2 for edit formula in excel it will be mute . Normaly when use F2 I can edit formula .

How to disable fn button ?

In bios cannot adjust do not see fn or hotkey function

So let me see if i understand,
You want to use F2 to still edit formula, but you dont the computer to be muted. That means, you want to remove the function of F2 to mute the computer, but still want to be using it to edit formulas?
Did you try to press FN+F2 and see what happen?
Or if you can clarify exactly what you want so i can understand.

Also if you can send me a picture of the place in Bios where you are looking for the Fn keys
