TPMS is mandatory in the USA as per FMVSS #138. Tampering with or removing the TPMS warning light is an offence which could result in a fine. I doubt any shop would disable it and risk getting fined. You might also find it difficult to find a shop that will remove the TPMS sensors for the same reason.
We can thank the Ford Explorer and Firestone tire issues of the early 2000's for the troublesome TPMS system we ended up with.

It seems some mfg's have gotten a better grasp of it than others. That being said, the TPMS sensors on my Rogue have been trouble free.
