No, you cannot manually disable ANAFI series drones GPS.
ANAFI series drones do not need a GPS fix to take off.
However, always be especially careful when you take off your drone without a GPS fix, as it will impact the Return To Home (RTH) safety feature.
Please refer to What is the smart RTH function? and How do I activate the Advanced RTH settings? for additional information on RTH.
Flying without a drone GPS fix may impair the flight stability and it disables the Follow Me mode, as well as assisted and automated flight modes.
