No switches that I`m aware of. When I go to France I normally fit a set of beam deflectors. The type that stick on and are very hard to get off without leaving adhesive on the lens. If you look at the lens there is a small circle or dot which according to the instructions with the beam deflectors is a reference point for attaching the deflectors.
Last time I went though I just stuck on some insulation tape and turned down the headlight beam and never had a problem
