After Su 7 I have problems with TBM 930 v0.6.1: I can not make dissapear steering wheel, can not put any VS up/down, etc.

Yes, that is why when you go to the mod in flightsim.to it says in big red shaded area that this mod has not been confirmed to work with SU7, which means we need to wait for the developer to update the mod and until then use the standard TBM930 that came with the game.
