The new version (2.3.0) that should be out very soon will have a way to force the focus on P4 Pro, Mavic and X5 (two finger tap on the video preview). This will allow you to pause the mission and do an autofocus even if the autofocus setting is turned off in the settings.
The aircraft will automatically do an autofocus at the point directly over the takeoff point and any further focusing will be up to the user.
