What is the privilege to maintain supplier contacts?

Summary:

I want to create a custom role to allow procurement users to update supplier contacts without creating a Segregation of Duties conflict. Is there a specific privilege to allow updating contact information, but no other informartion on the Supplier profile?

I saw this previous post but, back then, there was no role available and the information provided on the response was a link to a document that I cannot access.
