How to remove Employee Rating and Manager Rating only on Summary section

Hi to all,

on the Performance Document, I'm trying to remove the  Employee Rating and Manager Rating only on the Summary Section of Goals and Competencies.

Using Page Composer, if I unflag the visibility checkbox I can't see all the ratings on the page.

I tried to use these EL on show Component settings:

#{attrs.showMgrRating and evalItems.bindings.Name.inputValue ne null} (on Manager Rating)

#{attrs.showEmpRating and evalItems.bindings.Name.inputValue ne null} (on Employee Rating)

and it seems to work correctly but when I evaluate other ratings (the ratings on competencies and goals must be mandatory - comments are optional) and click on Submit button, an error message appears:
