Disable Rear Audio Controls

[Broncos7]

Is there any way to disable the rear Audio controls in a 2019 Expedition (not referring to models with the 2nd row console)?

It was very easy on my 2012. Neither google nor the manual seam to have any way to do it on a 2019.

Owner’s manual?

In my Explorer, you pressed a couple of the radio preset buttons at the same time.
