There is no adjustment in the headlights so the solution is a pair of blanking stickers.
I took my Plus Four to BHM who didn’t at that point have a certain answer and together we checked the beam pattern, and so located the correct position for fitting a pair (trimmed to the round section only) of the widely available stickers to mask the dipped beam left throw. You can do the same easily by parking close to a wall or garage door. The kick up in the beam pattern should be quite clearly seen. It’s perhaps a rough and ready method but is effective (and I doubt any Police officer on the continent is going to take issue if you have made the effort and tried to get it right). The adhesive is pretty strong so they should stay in place for your trip.
