I managed to remove the virtual cockpit by editing the model.cfg for the aircraft. I use The Steam edition,
Using the A320-NEO as an example ,find the model.cfg in
C:\Users\username\AppData\Roaming\Microsoft Flight Simulator\Packages\Official\Steam\asobo-aircraft-a320-neo\SimObjects\AirPlanes\Asobo_A320_NEO\model
Open the model.cfg
edit the lines below
withInterior_showExterior=true ,to
withInterior_showExterior=false
this should remove the aircraft model .
interior=A320_NEO_INTERIOR.xml ,to
;interior=A320_NEO_INTERIOR.xml
this should remove the vc .
