Synchronization of Garmin Connect and Zwift

Hello dear support community.
Look, I have a Wahoo Kickr Core machine, maybe you know how to do it, if I connect the machine to the watch (via Garmin connect) and start a specific workout in it (with the required watts and time for them) and at the same time start riding with it bike in Zwift, how to make the machine give load only when training from the watch (from Garmin connect) and not from Zwift itself, i.e. without jumps of load on descents and climbs? ))
