What is the delivered row level security view for Supplier search record on a Supplier Add/Update pa

What is the delivered row level security view for Supplier search record on a Supplier Add/Update component.

Looked into SEC_VIEW_NAMES table and didn't seem anything relevant for this. We have a Supplier setup shared by all BUs, would like use primary permission list to restrict viewing of confidential supplier. So was thinking to look at security view of the supplier search record and modify it.
