No. The closest thing that fits your request is the “Close session” feature (accessible from the OPTIONS menu), which kicks all users except the one who performed the close action. To achieve what you want, you would need to kick all non-moderators manually.
However, we have added this request to our roadmap. We imagine you would see an additional pop-up asking you if you want to “End session for all users”, “End session for everyone except Moderators”.
