From a technical perspective Tesla very likely could disable the upstream USB port that the center console module connects up to. (I don't really know anything about the Model 3's computers, but I work on non-automotive computers and operating systems, including various aspects of USB functionality.)
I'm assuming it's a full USB topology all the way from the MCU, but even if it's something else between the center console and MCU, I'm sure they could disable USB data on the center console in some fashion if they really wanted to.
It'd be pretty nasty for them to do that, but damn, they set a bad precedent already with passenger lumbar...
