Registration during webinar practice session

I started a webinar practice session a few days before my webinar was scheduled to begin. During the practice session, I heard from a registrant that the registration page stated that the webinar had started, with a button that said "register and join" instead of only "register. The registrant was confused since it appeared that the webinar had started days early. Is there a way to disable the "webinar has started" notification and "register and join" button during a practice session to avoid confusion?
