I enable the dfs service so I can keep my drone at a certain distance during a proyect, but when I was trying to arm the drone, the qgc show me the alert avoiding system not ready pre-arm check failed, and I noticed that the configuration inside the drone said "send voa to qgc false", and then I change it but it didnt affect the message
