Assign VIP to server in Azure Fortigate

Hi,

I'm using a spoke and hub topology in Azure with HA A/P Fortigate. Some of our servers need to use public IPs to communicate with external servers. I checked the documentation but couldn't find the information I need. Is it possible to assign a VIP to a server in Azure Fortigate?

The traffic flow is: Server > Internal LB > NVA Fortigate Firewall > External LB > Internet.

Thanks!
