Block access to individual habpanels

Using openhab 3 and nginx, I managed to restrict access to indidual sitemaps, both using the browser and the android app, by using the IP “allow / deny” nginx-functionality.

I also managed to block access to Habpanel as a whole.

Is there a way to restrict access to individual dashboards or panels? I would be able to do this both from the browser and the android app.
