Pulling employee information from Skills and Qualifications page to be used in EL expression

Summary:

We have a need to pull either the employee name of employee username from a page to be used in an EL expression, but it does not appear to be possible.

Content (required):

We have a requirement to make the Skills and Qualifications responsive page within Talent Profile Read Only for Line Managers.

We want the employees as well as HR Admin to be able to edit the Skills and Qualifications page.

Initially we used an EL expression to the following Skills and Qualification page to make it editable only by HR admin.

My Client Groups --> Talent Profile --> Skills and Qualifications
