Thank you for getting back and apologies for missing on your additional question here.

There is a solution available for this which you can explore on Azure Marketplace managed application that implements a Cloud Based Virtual Switch which enables Multicast on Azure. Please find the link to the application below: https://azuremarketplace.microsoft.com/en-us/marketplace/apps/swxtchiollc1614108926893.cloudswxtch-vm-001?exp=ubp8&tab=Overview
