Patients often try different types of mouse due to hand pain or stiffness from their DD. I myself switched to using a mouse with my non-dominant hand when I had related problems with the dominant hand. Eventually my DD became bi-lateral anyway. I also always use a mouse instead of a trackpad on a laptop. I think the risk overall is more to do with tendonitis than exacerbating progression of DD but that's just personal opinion of how it affects me.
