The P2006T does have carb heat and it is via hot air ducted off the exhaust muffler. Controlled by levers on the throttle quadrant.
In my experience, the P2006T (like most Rotax installations) suffers little from carb icing once the engine is up to operating temperature.
Heated carb systems are not certified. My own Rotax has Conair coolant jackets around the carb outlets so the carb body remains warm. Negligible power loss as it isn't hot air being fed to the engine, the warmth just prevents ice from forming.
