Deactivate the storage of conversations

Version: Rasa X 1.1.0

I’m running a Rasa X installation that is used through the webhook. The data sent to the bot contains sensitive data. Therefore I want to deactivate the storage of conversations in Rasa X (at least those coming from the webhook). Is there an easy way to disable them, maybe in a configuration file?

As far as I’ve understood the conversations are stored in the tracker, so I tried to comment out the tracker_store values in the endpoints.yml but this didn’t helped disabling the storage of conversations in Rasa X.
