My twice-exceptional son with dysgraphia retains more when he does not write notes himself and instead listens to the lesson. He is a very strong auditory and visual learner and trying to take notes only distracts him.
I don't have any 2eness, but I also find that taking notes reduces the amount I retain, especially if I have to take extensive notes. Lectures at university were pretty much a waste of time for me, back in the day when they didn't provide handouts, because I couldn't both write and think, and I had to write, so... These days, I take either a computer or a
small piece of paper on which to write not more than a few words or a URL.
