How to make National Identifier view only and not editable for some role?

Summary: We have a requirement to make National Identifier(SSN) Editable by few roles only, and other roles can view them but cannot edit it.

I have tried through Personalization and used the below EL Expression for the Pencil icon(to make it appear for specific role only). But it's not working.

#{securityContext.userInRole['Payroll Administrator Data Role','Payroll Manager'] }
