How do you make options on drop down list hidden from some roles on Additional Person Information?

Summary:

We need to make the Additional person information page available to update to employees but only certain one option on the Info Group dropdown field available to select by the email - ideally i'd like only one option to be visible to the employee.

We're not using Redwood yet. We want to get the employee to update some information that's held on the Additional Person Information page - but only specific info - the other things on that page are just for HR. We'll be sending out a journey/email to ask people to update the information, but i'd like to be able to point them to the page and the employee not have any other options to select from (so it's as easy and not confusing as possible)
