Brake Controller Recommendation for 2023 Mercedes GLE 350

Question

Question:

I want to install a brake controller on a 2023 Mercedes-Benz GLE 350 and am interested in a Proportional Controller. A controller recommendation is requested. Also, the cars connector to connect to the controller Im assuming is under the dash near the brake pedal. Im a bit concerned about that area as there is an airbag panel under there too. Any advice will be appreciated.
