Hello,

If you are working with user roles, you can hide the "New record" buttons by removing creation rights for specific user roles on the related table.

Another solution could be to hide your relationship field and make use of a dynamic choice field to list the related table records. Then use the "trigger after update" to modify the relationship field by a script. Users would never see any "Add Record" button ...
