X870E board owners, have you switched off your VRM/MOS fan?

I've only had my Nova board a few days and I can occasionally hear the VRM/MOS fan spinning up. It's not loud, I'm just sensitive to such things, and it only spins up for 30-40 seconds before going back to sleep for ~10 mins.
Is it safe to disable in the BIOS? (I'm not overclocking etc.)
Is there a program that can monitor/disable this particular fan whilst we're in Windows and don't have to re-enter the BIOS?
