Record activity without wearing the watch

to the topic: I am playing ice hockey, but for obvious reason I do not want to wear my watch during the game. So when the season begins, all my training metrics are devalued, because garmin does not know about my activities and instead think I'm lying on the couch. So the question: is any of Garmins chest bands capable to record activity by itself without wearing the watch? So I can leave my watch in locker room (or on the bench) and record the activity during game only by wearing chest band and then sync it to my garmin acount and get training effect from this? Or is there any other way how to do this?

My watch is a Garmin Fenix 6, if that has any meaning
