2022 Silverado humming noise when A/c is on

[Trip3z]

I have a brand new “refreshed” Silverado LTZ Z71 that makes a noise similar to the noise a power steering pump would make that’s low in fluid. I’ve seen somewhere online that this “is normal” ?!? Never heard this noise on any other truck I’ve had. It goes away soon as I turn the A/C off. Anyone have same issue?
