To answer your question directly, you can use the ObjectDataProvider to call a method for you so you can work with the results:

xmlns:System="clr-namespace:System;assembly=mscorlib"
xmlns:Windows="clr-namespace:System.Windows;assembly=PresentationCore"

...


    
        
            0
        
    

You should then be able to access the result like this (but you'd need one of these for each TabItem):

However, it's generally not good practice to manipulate UI properties such as Visibility in code, so a better idea would be to use a BooleanToVisibilityConverter to Bind the Visibility properties to bool values as @Highcore suggested. You can see an example of this in the Binding a Button Visibility to bool value in ViewModel post here on StackOverflow.

In my opinion, an even better solution would be to simply provide one view for every view model.
