Asalaamu alikum brother,
It's nice you care so much about your brother to want to help him so much. You already mentioned that you are making dua' for him and this is the best thing you can do.
Be careful not to argue too much. I think the best thing you can do if you have some disagreement, is just simply state your position backing it with Quran and Hadith and do it of course in a patient way, and leave it for him to consider. If you know other brothers who can speak with him as well, maybe that will be beneficial too.
May Allah guide us to the right path and forgive our shortcomings. Ameen.
