The previous answer is not for D5L unfortenately, it's for Båtførerprøven.
Here is a post from 2017 answered by @Poseidon that does D5L courses:

I am operating Baatskolen POSEIDON and I have the same question coming up from time to time, especially here in Stavanger with a considerable amount of foreigners.
The answer is always the same: to the best of my knowledge there is no approved school with D5L available in any other language than Norwegian. Neither do I know any suitable learning material that could be used for setting up such a course. To build it all from scratch would be too much work and cost.
Sorry that I can not give you a more positive answer.
Check in on this thread now and then to see if someone can help, I could not find anyone when googling.
