How To Disable the Generic Play Button on Chrome for Courses Published in SL3

With the recent SL3 update, a feature was added that inserts a generic play button ahead of the published course when viewed in Chrome.

Enhanced: We added support for Google Chrome 66. If audio or video content in your Storyline course stopped working in Chrome 66, install the latest update and republish.

Is there a way to prevent Storyline from publishing with this? We already have a workaround with a custom "Start" slide, users don't need both. Is there a place to turn off this functionality? This will be going out to a huge audience, and this functionality can be confusing/messy. I don't need it. How to turn it off?
