Emmm, you are not allowed to change your setup from Qualy onwards - except for front wing and tyre pressure.
The reason why the holes are open is probably because it is a test session and at test sessions you test quite a lot of settings.
That's not strictly true. You're not allowed to change your setup between the end of quali and the
start of the race. After that you can do what you like, except in a 2hour F1 race the implications of changing many things are much worse than in a 24hour endurance race. Hence they they tend not to change suspension settings mid-race. (I don't think anyone yhas never tried to - anltho I don't know that for a fact).
Silence is golden when you don't know a good answer.
My bad! 
Sorry guys.
