Multi-BU profile option makes BU mandatory on Knowledge Articles — need workaround generic articles

We're implementing HR Help Desk Redwood for a new client with multiple Business Units. We need HZ_ENABLE_MULTIPLE_BU_CRM enabled to support other BU-dependent setup in Help Desk Redwood.

Issue: Once enabled, BU becomes a mandatory field on Knowledge Article creation. However, a large portion of the knowledge base is generic — content that should apply across all BUs (e.g., general HR policy, system navigation) rather than being tied to one BU. We cannot create Knowledge articles for each BU as that will be difficult to maintain in future phases.

Is there any workaround to make the knowledge articles available for All and bypass the BU tagging?
