Restrict property to be read-only


Can someone tell me if a script can be used to restrict property to be read only for my profile? v8.1.3

We have a need to ensure that internal employees don't edit certain things since most data comes from HR.

External users should be able to update there info. I search the technical documentation and did not see where this is referenced.

Can this only hold true or false? If I use editability script on the template it does restrict but that also restricts me or any admin from editing the field in manager.

 Thanks and any help is appreciated.
