I’m looking to convert my manual climate control in my 2021 Silverado Custom to the auto climate control.  Has anyone one done this and knows what is involved and what is needed

If it's anything like previous trucks, it's not really possible. The wiring is different and the BCM function is aswell, we can't program the BCM's and GM won't just let you do it either.

Welcome to the forum. Dont even try this. As Cam said the BCM is not programed for this and no GM Dealer will help you. You have a "Work Truck" and it was not designed to have automatic climate control. Besides that my manual climate control works just fine.
