M365 Defender integration with Azure Expressroute

Microsoft Defender for Endpoint does not provide integration with Azure ExpressRoute. While this does not stop customers from defining ExpressRoute rules that enable connectivity from a private network to Microsoft Defender for Endpoint cloud services, it is up to the customer to maintain rules as the service or cloud infrastructure evolves.

Question:

Is there a possibility to route the defender alert/data/etc back to ms365 defender backend through Azure Expressroute? and if yes, what is the required approach?

Many thanks in advance!
