How to disable seeded Customer menu?

 Hi Team,

1.Created a custom resposnibility XX Customer
2. Disabling grant or excluding functions of Standard customer form menu
from custom responsibility mentioned above is not disabling the functions in Customer > Standard form

Menu :>>>Customer Submenu > Customers : Sub functions
Functions:>>>
Customers: Profile
Customers: Telephones
Customers: Contacts
Customers: Payment Methods
Customers: Banks
Customers: Relationships
Customers: Address Profile
Customers: Address Contacts
Customers: Address Telephones
Customers: Address Payment Methods
Customers: Address Banks

However  OA personalization  use disables In  R12, hence able to restrict access to the Customers screen for different users.
Some user should be able to view and edit Customer Profiles and Credit Limits, while other users should only be able to view
