RZR clutching to reduce engine RPM under low loads

I have a 2012 RZR 800 50" machine with 26" tires/rims that widen the machine to 55": I mostly drive around on the logging roads in BC and the jeep trails in AZ in the winter (mainly for access while bowhunting). I don’t need the RZR to be running at +3,500 RPMs constantly with all 53 HP on tap instantly. I’d like to do more "idling" around at low RPMs like I do with the Honda Rubicon and Rancher ATVs I have. That is not possible with stock clutching in the RZR and probably contributes to extra wear on the engine and more fuel consumption (in my opinion). Note that I added a second Kolpin muffler for a quieter ride, and it works well.

So is there any after market options I should be looking at? I recall a ride in an 800 Ranger a few years ago and it seemed to be "geared" (clutched) about like what I’d like from the RZR. Any cross-over on parts there? Note that I don’t want to burn the belt either so asking for expert advice. My RZR is my first ATV/UTV with a belt drive.

All in all I like the width, ride and handling of the RZR for my purposes, just not the wound up engine.

Thanks for the comments and help in advance!
