Can you disable the TPMS system via a physical switch

My chime in was just related to the tangent question, but I would submit to everyone that it takes a hell lot more to unseat a bead than might think, even if going as low as 12-15psi without beadlocks.....or basically what I'm saying here is the TPMS alert is really only pavement-related IMO. Even when airing down that low it takes some real sideways force to roll that tire and pop the bead. The whole point of lowering the threshold alert for me is for folks that run lower tire pressures with larger tires. I run my 37s around 26-27 psi cold, and when I had 35s it was more like 29-30. It gets annoying to see that alert when you have your tires right where you want them for normal driving on pavement.

I often air down to 17 for washboard trails & rocks, and much lower for loose blow sand.
I think you can program the TPMS PSI warning level to whatever you want to via an app & an iCar Pro Bluetooth LE bluetooth thingie inserted into the ODB port. It's really easy. I used JScan app for iOS or Android and the Bluetooth thing they highly recommended. Cost was something like $30 for the Bluetooth ODB thing & $20 for the JScan app (per vehicle VIN#). Well worth it & there are a number of other fun adjustments you can do too. Plus it's a code reader, & you can use it to program new keys!
You do not need to leave the ODB thing attached, it is just connected while you are making changes.
