Supplier master segregation

Summary:

We have 2 ledgers and 2 business units in one instance. At supplier level, data can be accessed by both business units.

However, the ask is to restrict the supplier data at BU level as one BU do not want to see/modify the supplier data of other BU.

I understand that restriction is possible only at site level. Please let me know your inputs on this.
