How to hide calculated rating for Employee and Manager in performance document.

Summary:

Dear Team,

Our client requires that only the Calculated rating field is removed so as to not show the calculated rating value in the Sections Summary and Overall Summary section of both Employee's and Manager's view.
But the employee and manager should still be able to do click the "Calculate" button and view the rating in the dropdown.

It was possible before using Page Composer RUI

But with the current VB Redwood, we cannot find any RuleSets, components or business rule for the Performance Document page that allows us to hide it.

Are there any ways to achieve this ?
