When renting a car, there is an option to indicate whether to take the car out of the country and where to go. If you write down the country you are going to, it should be fine. I rented a car in France before and drove to Italy and Switzerland. I didn't have enough time to go to Germany ?

Done, they will mainly check whether your visa will become invalid due to crossing borders, which should be fine in Schengen countries.
