Turning Off RTH Warning

[MRomine]

The warning says, " Current RTH route will pass a no-fly zone. Pay attention to the aircraft's position to avoid RTH failure." I tap and close it. Why does this warning keep appearing every two to three minutes? I only need to see it once, not again and again while I am flying a job. Is there a way to neutralize the warning?

Here is a screen shot from my Smart Controller. Can this warning be turned off? I have an Unlocking license for this area and it is enabled.
