I see in the manual the dynamic roof weight capacity is 220 lbs for the 2022 Suburban Z71, but I wasn't able to find any information about the static capacity (when the car is not in motion, such as camping). Does anyone happen to know this information?

 

It is the same. My Tahoe is 200 lbs. and no mention of dynamic. 220 is the limit, parked or driving and should say not to have load overhanging in any direction as not to have wind related issues.
I would not even consider a roof top tent on stock roof racks.
