Redwood page-additional person info customization based on role

Summary:

In Oracle HCM Additional Person Info page, we have EIT fields in drop down and i want to customize the Add operation based on the roles. I need to do this using visual builder option

Content (please ensure you mask any confidential information):

Role based customization needs to be done here. Example: When Highly Qualified Status is selected only Talent AcquisMgmt Administrator should be able to add or edit it. other role should have only readonly access. Similarly when other drop down value is selected ,Talent AcquisMgmt Administrator should have readonly option.

I tried to apply some condition in add button but it is not controlling based on drop down value.
