Is there a way to make "find my iPhone" not work? Is there any possible way to disable find my iPhone without just turning it off?

My parents are extremely clingy (in a very bad way) but luckily I am at least privileged enough to have my own iPhone. 

Every once in a while my parents use the "find my iPhone" app when they're nosing even though they promised to only use it in emergencies.

I'll be grounded if I turn it off, but they wouldn't know if there was somehow a way to just say "iPhone cannot be found" or something. Perhaps if I jailbreak it?
Remove an iOS device or Mac by turning off Find My iPhone

Remove a device from Find My iPhone by turning off Find My iPhone on the device.

On an iOS device: Go to Settings > iCloud, then tap to turn off Find My [device].

Note:   You can also remove your device by turning off iCloud completely on that device. Turning off iCloud turns off all iCloud features on the device.
