Accounts Payable wants to limit the availability to create and modify suppliers

Summary:

Currently all of accounts payable has the access to create and modify suppliers. They would like to narrow it down to a few users.

I removed all data access from an individual supplier manager role thinking this would create the desired result. User was still able to create and modify vendors.

What do I remove from said user so they can no longer create and modify vendors.
