How to make Account Type on Mobile App Read Only

Summary

Mobile App scripts to make standard field read only

Content

Our requirement is that our sales team can create new accounts of type Prospect which is the default value but should not be able to create new accounts of type Customer so we would like to make the field read only.  We have made the Account Type standard field read only in the SUI using page composer but need to make that same field read only in the mobile app.  Has anyone accomplished this or can offer how it can be done.

Thanks
