Hello Blink,
With the "UI control" node standard on node red you can make jumps from one tab to another for instance, what makes you can physically display a button on your dashboard that directly inject a value on the "ui control" on your flow and on your dashboard will jump to the specific tab you wanted, the same can be done to move back or whatever.
Also you can make that a specific hour or after specific time with no action, it moves directly to a specific main tab.
I think this is an easy approach to what you are trying to do, however as mentioned by dceejay, this will not hide all the tabs from the left menu on the dashboard.
Regards
