It takes years sometimes. You have to give people time.
I don't think it's possible for a presuppositionalist to ever become rational on the topic their presupposing. It's a rabbithole that doesn't allow escape. I'd like to be wrong about that, but although I've met many former theists and am one, I've never met a former presuppositionalist, no matter what flavor of Christianity or Islam they espoused. Once you buy that presupposing something is actually an argument, you've given up any tools that would have allowed you to reason your way out of it.
