The only way to turn off GPS cell phone tracking is by turning off your cell phone. or remove the GPS receiving antenna
Depending on the situation needed to turn it off.
weapons,paint,well you can take a phone on the plane but you have to turn it off.

There is no way to remotely activate a switched off phone.
Your phone will only have a GPS tracker if it has those capabilities. If you do have a GPS on your phone you can go to the settings and under GPS you can turn it off. Otherwise a cell phone company can track you to find you if they are approached by law enforcement and there is nothing you can do about that.
