how to Hide Check-in Tab on Performance Eligibility Page

We are currently facing an issue , where the Check-in tab is visible on the Performance Eligibility page, accessed via Navigation: My Client Group > Performance > Performance Eligibility. As per our business requirements, this tab needs to be hidden, but we are unable to locate any configuration or personalization option to achieve this. We request Oracle Support to provide guidance or a solution to hide or disable the Check-in tab from this page. Kindly investigate and advise on the necessary steps or configurations required to resolve this issue.
