NUX - prevent edit and adding certain phone type

Summary

We want to load Work Phone and NOT allow employees to modify

Content

We load our employee work phones through HDL. We want to restrict the phone number loaded to read only and not allow them to add a new Work Phone Types (we have a process out side of Oracle HCM to update Work Phone, which we would them load through HDL)

So far my attempts only make all phone numbers read only
