Yes, you can add console.set_idle_timer_disabled(True) to your setup method to turn off auto-locking when your game starts.
You should also add a stop method to your scene (if you haven't already), and go back to the normal behavior there:
class MyScene (Scene): # ... def stop(self): # Note: This will be called automatically when the scene is closed. console.set_idle_timer_disabled(False)
