Reba RL Damper Motion Control Help

I have a Reba RL fork with a motion control damper. The remote broke, but I don’t want to replace it. I would rather just have a switch that is on the shock itself, like my old Reba had. But I can’t seem to find the part, even on the sram trailhead app. Maybe it doesn’t exist? Or maybe I have to totally change out the damper?

The unit is a FS-Reba-15B-A9.
