Azure Purview Managed Vnet, Vnet Integration Runtime and Managed Private Endpoints

Thanks Vishal for updates,

As we were looking forward to secure purview account using managed VNET & private endpoint connection .
But we are looking to get this implemented either using powershell or REST API, which i find these modules for creating managed virtual network and integration runtime is not opened for Powershell or REST interface.

Only way to have this implemented is via Purview governance portal.

Can you please help me out if these features can be implemented via powershell or REST.
