How to restrict a recruiter's access to internal candidates info and activity

Summary: We have a requirement to restrict the access in ORC for our HR Advisory team, so they can't access (even view) their colleagues' (or those currently within the HR department) internal candidate profile/activity (i.e., they should not be able to view job applications in ORC of their HR colleagues). Is there a way to achieve this?

Their current ORC role allows them access to anyone in the candidate database (via candidate search or candidate pool), as well as all job requisitions or job offers even if they aren't part of the hiring or offer team.
