Contolling Task visibility for Line Managers in Journeys

Summary:

Asking this question here again because I'm not getting approprate response when I logged an SR 3-32921948881. How can we hide the employee tasks from line managers for Enterprise Onboarding type journey. I have set Checklist property to 'hide' for Other's Incomplete tasks for Line managers, but still it shows up for the line managers.

Content (required):
