That's a good question because the puck spacing changed for the Fifth Wheel Prep Package on the 2020 models of GMC and Chevy trucks, which means you do need a specific adapter with your Hijacker.

The correct Demco Hijacker for your 2020 GMC Sierra 3500 is the Demco Hijacker Autoslide 5th Wheel Trailer Hitch # DM8550034 (18,000 lbs) or # DM8550035 (21,000 lbs) and to mount this in your '20 Sierra you will need the Demco 5th Wheel Rail Adapter for Chevy/GMC OEM 5th Wheel Towing Prep Package # DM6333.

The only difference between the two Hijackers is the 18,000 lb or 21,000 lb towing capacity, and they are otherwise exactly the same, with the elite jaw system that is reinforced via a 3/4" solid steel bar, and convenient automatic slide so you never have to get out of your Sierra just to make a tight turn.

I have added links to a couple video reviews for you to check out as well.
