Genesyscloud_knowledge_document permission drift in Terraform

Quick question about the genesyscloud_knowledge_document resource. Provider v1.42.0 fails to set access_level to INTERNAL during apply, reverting to PUBLIC immediately after. Terraform 1.5.7, AP-Southeast-1.

Error: 409 Conflict: Document access level cannot be changed to INTERNAL without removing existing external references.

Any way to force this via HCL without manual cleanup?
