Welcome to the Wefugees Community and thank you for your question.
The driving license itself might be offered in English. If you want to work as a truck driver, you need to do a so-called "Ausbildung zum Berufskraftfahrer" (apprenticeship to become a professional truck driver). Only having the truck driver's licence doesn't allow you to work with it. You can apply for a grant by Agentur für Arbeit for this apprenticeship as well.
My colleague was providing some information on this topic here.
I have some doubts that it is possible in Germany to complete the apprenticeship (since it has a schooling part) completely in English. I tried to make some further research, but unfortunately I couldn't find any interesting tipps/information yet.
I will keep my eyes open and maybe other community members can share some experience/knowledge as well.
All the best,
