As the title says is it possible to turn off the auto return home function when losing signal on the mini 3 pro? I have a flash light attachment and would like to fly this in a large cave but given the nature of rock blocking signals incase it bugs out i dont want it automatically flying into the cave roof lol

You can set it to hover if signal is lost.

Hello there cosmiccomet180. Good day and thank you for sharing these interesting information with us. Just a friendly reminder that DJI do not recommend flying your DJI Drone indoors and caves as the environment may have interference and caused an incident and also during low light condition as the vision sensors may not work properly. DJI suggest to choose an outdoor open area where the GPS is good, no magnetic interference, to fly the drone and check if all the functions are normal. Thank you and fly safe always.
