is it possible to enable fortigate 200D http-ip-header fortigate 200d

[N1417]

I'm using FortiGate 200D. I want to see the IP addresses in my web server that is sitting behind the firewall, but the firewall that I'm using, which is FortiGate 200D, is not passing the IP addresses so I can use the X-Forwarded-For in my logs. I saw the solution is to enable the http-ip-header. So is it possible to enable it in FortiGate 200D? Is this feature available in FortiGate 200D?

thank you.
