I have a mild case. What I do is stretch my fingers many times per day. I use “yoga hands” a device I bought on Amazon. It’s good I think because it allows the stretch to be very tight or whatever you are able to do. Search for “ finger separators for hands” and you’ll find LOTS. My father and brother had bad cases of Dupuytrens. I’m lucky to have only a mild case. I think the stretching helps
