@jimvfrmoto750 yeah I did a NFZ removal guide (and rooting) for the Phantom 4 over here: How to root your DJI Mavic Pro, Phantom 4 and Inspire 2 using DUMLRacer and completely remove NFZ
And the Phantom 4?parameter mods are in this post - @mickydd this is the one you need for your Inspire 2 as well: How to change flight parameters on a DJI Mavic Pro, Phantom 4 and Inspire 2
