Managing Multi-Tenant Azure/365: Workarounds for Cross-Tenant Limitations in Purview and Fabric

I am working in a Microsoft  Azure/365 multi-tenant setting due to some constraints. I am using Purview (Tenant1) and Fabric (Tenant2), M365 in (Tenant 2). I'm facing issues with various solutions due to cross tenant limitation for eg: Data Quality Connection, Metadata ingestion, lineage, etc.
To overcome this I am exploring various workarounds.

Key Question:
1. Are there proven workarounds or solutions to manage data estate in this scenario? (Can't merge /migrate tenants)
