Any way to change the tailgate coding on a W205 estate?

[C350ezoom]

Ever since I bought my W205 (C350e) estate I've had incidences of finding that the tailgate has opened itself. Presumably this is because a key has pressed the tailgate button while in my pocket. Is there any way to re-configure the car so that the tailgate will only open from the key fob if the car is unlocked?

Cannot change the settings as you explained.
