Set Name Field to required or not required via the API

Hey Guys,
I saw that I can add/update/delete custom fields via the api. For Custom Fields I am able to change a specific custom field from required to not required.

Sadly I haven't found any option to do the same for the name field.

My users can choose if they want to show a First Name Field and if it should be required or optional. But if the user sets the name field to required inside Campaign Monitor and forgets to change the settings of my applications to required as well I won't be able to subscribe users.

Is it possible to change these settings for the name field through the API?

Thanks and best regards
