TRX squeak @ idle

Asking for a friend: 2021 TRX, has a noticeable squeak at idle. To me it sounds like an idler pulley bearing or maybe even something with the supercharger bearing. It does change slightly with RPM but you can't really hear it in the cab while driving (windows up). He's taken it to the dealer and was told that it's something to do with the vibrations of the 6.2 and how it's mounted in the truck so every TRX has the same noise.

Any ideas?

*edit* it's a 2021
