Garmin GTX 330ES transponder - in "off/standby mode" will it still transmit ADS-B data?

I have a transponder (GTX 330 ES) where the 91.413 check is about to expire. For various reasons, the check may not get done by the end of the month.

I believe 91.215c allows me to just not turn it on after that time, and be just fine legally. This is just a training airplane and I can easily avoid flying in transponder-required airspace for a little while.

But what about the ADS-B portion? If I put the transponder in OFF or STANDBY, does it still broadcast the ADS-B signal and therefore be compliant with those rules? I have to imagine that the answer is no, just based on logic (since it's "off" or in "standby"), but I couldn't find anything in the user's manual.

And that would run afoul of 91.225f, which requires that if it's equipped with ADS-B, it must be turned on.
