If there’s a German code that would work as you intended (if I got you right) but it doesn’t for you, since you don’t live in Germany, would it work to make the machine believe it is located in Germany?
They might have hardcoded a location into it, then you are out of luck. But maybe they determine it via the internet connection you use to update? So you could potentially have it connected to a VPN through your router, which fakes a German location? Probably too simple a solution.
You don’t use the internet on a laptop?
