deploying a Fortinet FW in Azure Virtual WAN hub for internet gateway

[sumitava]

Hi Guys,

We are currently testing Azure Virtual WAN with our existing SD WAN solutions, however we are not planning to use the Azure FW for the VNET security and was planning to deploy the fortigate FW as the internet FW on the Virtual WAN Hub so that it can publish the default route to Virtual WAN hub and all VNET & VPN sites uses this fortigate FW for internet breakout.

Is that possible? not able to find any document for the same.
