Ability to edit fields in the universal definition name style

Summary

Hide "Title" and "Middle name" in the universal definition name style.

Content

An Italian customer would like to hide the name types "Title" and "Middle Name" from the contact information for the candidate in the career site and, in general, in ORC transactions.

The ORC guidance states that, in Recruiting, the name format is based on the universal definition.

From the Task "Manage Person Name Styles" I see that it is possible to add other name types but it is not possible to delete the existing ones. 

Could someone tell me if there is something else to consider in the Manage Person Name Styles task to make the change or if there is a way to achieve the same result (i.e. hiding "Title" and "Middle Name")?
