Field in View linked to another View
Solution 1

You could try making the path for each display some kind of hierarchy and using Menu tab as the menu Page settings in order to display both views next to each other in the primary tabs of a page.

Example paths

mypath/view1 // Display 1
mypath/view2 // Display 2


Solution 2

Add a header or footer to the view in Basic settings and include the link to the other view.
