Limit users view of applications on the dashboard via API to NetSuite database

Setup
Database Connection to NetSuite>NetSuite Customer Contacts are created as Auth0 users when certain conditions are met>Data from NetSuite needs to provision/remove access remove access to/from certain apps.

We will have 4 portals set up and accessible via universal login to SSO Dashboard. All users do not need all 4 portals.

Can an API determine what portals to provide access to and have only those applications show in/on the dashboard?
