To disable the inner gate, press and hold the upper tailgate button for 3 seconds with the key fob near the tailgate. The turn signals will flash at which point it will indicate that the inert tailgate button is diabled. The full tailgate will still open but now there will be no accidental opening of the inner gate and risk hitting a ball hitch.
To re-enable the inner gate, simply repeat the process. With the tailgate closed, press and hold the upper tailgate button for 3 seconds with the key fob near it. The turn signals will flash and the inner tailgate button will be re-enabled to allow the opening of the inner gate.
Perhaps in the future GM will provide an over-the-air update that will enable 2019-2021 GMC & Chevrolet truck owners to do the same thing with their MultiPro or MultiFlex tailgates. But for now, as stated before, this only works on 2022 and newer trucks.
