It is really a problem when in a middle of the shot you pressing the M and Trigger button and the gimbal starts calibration ruining the entire shot, we're really need to disable this hotkey combination. Thx!

Sorry to hear this, were you aiming to enter the Sport Mode or Lock Mode when you pressed those buttons during the shot?  
When holding the M button or Trigger Button, it will remind the users by tapping an icon on the screen to stay in the Sport Mode or Lock Mode, then the users can release the button. This can also prevent starting the calibration from accidentally. Hope it helps.

the "Trigger" are for locking mode and "M" assigned to hold focus in FX3, both buttons are very handy to use.
also, once it enters in calibration by this hotkey, it clears all of the current values and the gimbal stops working until you perform calibration in a proper way. When you do event jobs, the shots you cannot repeat, that may be a disaster.
