Alarm System Question

When I took my older ML350 on a car ferry, had to switch off the alarm system's motion sensor to prevent false alarms. Does the current ML's alarm system have a motion sensor, and, if so, how does one lock the truck without activating the the motion sensor? Or, if the sensor can't be defeated, how does one lock the truck without arming the alarm system? Thanx in advance!

See US Owners Manual

See US Owners manual page 88-89 - called Locking the Vehicle (mechanical key) - that process locks the doors and tailgate but does not activate the alarm

If you have Keyless G also remove Keyless Go button so the rig stays locked even if you are in range and someone else grabls fdoor-handle/rear-tailgate

How much motion is needed to set off the alarm as I know the body of my truck has moved more than an inch or so on a rough landing
