This is absolutely false.  The car will automatically come on to boost the 12v battery if the voltage drops to 12.0 or 12.5v depending on if your car is early software or later.  I've documented this on my 2017 BEV.  There is no need for external interference.


Another thing I have documented (with my Bluetooth 12v Battery Monitor) is exactly what happens to the 12v battery when you remotely unlock and then lock the doors.  Please see this pic of the graph of the 12v in my car sitting in my garage and remotely Unlocking and Locking the car at 1pm and 2pm.  Note the voltage before and after each Lock/Unlock command.
