Shopify store chat, is there a way to turn it off during certain hours?

[797Performance]

We use the chat a lot, we have our hours setup, and after-hours it does  tell our customers that we are closed, but all night long I hear my office PC and my phone going off because they can still chat with nobody.

Is there a way they cant type to us afterhours?

seems as if the answer is no
