Hey William, thanks for reaching out. You can use the Curt TriFlex NEXT Trailer Brake Controller # C24VV (51146) in your 2020 Buick Enclave, but Curt doesn't offer a custom pigtail for that vehicle. You can still install the controller, but it will mean hardwiring in a new plug.
What you'll need to do is cut off the factory brake control plug and wire in the Universal Wiring Adapter for Curt Trailer Brake Controllers # C51515. That'll allow for plug-in installation of the Curt brake controller. That way you can unplug and remove the controller if needed.
What kind of trailer will you be hauling?

Curt Mfg. has recommended a universal harness #51531 which has some a few more features than #51515. I'm uncertain which is the best for my 2020 Buick Enclave. Could you provide some clarification? My cell phone number is 952-807-2552.
