Changing the visible/hidden default view from the user interface

Not sure this is already possible.

I wish that the default view could be excluded/included from the user interface (without having to modify the configuration file

What is the use-case?

to enable for me when I want to see it, but disabled by default when all family is using HASS.

This without the need for a computer, more easily from the UI

You can create a view for family members and they can open it in kiosk mode - this way they won’t see other views and won’t see the sidebar.
