Rims interchangeable?

Hi everyone. I purchased a new 1500 Denali. It came with the 22” rims but I need to swap these out. I would like 20” for the additional sidewall on tires.

Are the 20” rims interchangeable? I assume the Chevy and GMC rims are the same. Are there any configuration that need to be know such as bolt pattern or something similar?
