If your desire is to ensure the car is quiet when you start it, I don't know what your options are. As I understand it, the earlier years used a vacuum pump to operate the valves, thus I assume the vacuum would bleed off over night and allow the valves to be open at initial start. In later years I hear it's electrically managed, but do not know if there is still a vacuum component that would bleed down over night.

As I see it, the only point of the switch is to open the valves in non-dynamic mode, or close them at low revs in dynamic mode, so dynamic mode off and on can really do it all by itself. The valves will always open when you get the revs up, and at cold startup, but you can quieten the startup by selecting D early.
