Now in Public Preview & Targeted release: Teams Discover Feed

I need a way to turn off the Discover feature NOW. I'm getting dozens of pings from my staff who are confused by what Discover is and what it does. Some think their posts in one team are now visible to everyone because everyone has a Discover feed. I've tried to explain to them that Discover is more like a digest feed that summaries all of their teams, but they just don't get it. Now people are angry at me and I have managers who are breathing down my neck because of this.

I don't want this feature in the pipeline. I need to disable this NOW or I'm going to lose my job.
