laravel 8 update eloquent relationships hasmany - php

Question

My UPDATE function is as follows; I manually set some fields in the users table. In other words, it is necessary to update only the name part from the incoming request. If the lawyer has been removed from the edit form, it must also be removed from the users table. If the lawyer name has been updated, it should also be updated in the table.
How can I complete the update process.
