Question on Siri activation; if no answer, then a suggestion

This is my very first experience with an iPhone as I'd been using Android since 2011.

Is there a way to schedule when Siri can listen for "Hey Siri?" I work for Best Buy's mobile department and I'm handling customers' phones pretty much all day, and more often than not I'm accidentally saying something similar to "Hey Siri" or specifically saying "Hey Siri" when discussing features on the iPhones.

I would love for there to be a feature where we can schedule when Hey Siri would not activate Siri. For right now my work-around is just to disable it until I'm off-shift, but (again) more often than not I completely forget about it after a long day of work.
