Can a FortiGate act as a standalone IPAM Server

Hello everyone,

I have read the documentation and multiple community posts, but I'm still confused if a FortiGate can act as an IPAM server alone?

The documentation says the FortiGate can act as a standalone IPAM server:
https://docs.fortinet.com/document/fortigate/7.4.8/administration-guide/166728/configure-ipam-locally-on-the-fortigate 

But I also have seen community post that say the opposite:

https://community.fortinet.com/t5/Support-Forum/IPAM-feature/td-p/312696 

https://community.fortinet.com/t5/Support-Forum/IP-Address-Management-IPAM-feature-on-Fortigate-enable/td-p/260963 

So can a FortiGate be a standalone IPAM server or no? The documentation isn't very specific for a standalone FortiGate that manages multiples networks or maybe I have missed that part. Also when I configure an interface on the FortiGate for IPAM, with rules and all, it doesn't configure the DHCP server on the interface. It leaves the DHCP pool blank even though screenshots with FortiIPAM show a FortiGate gets an DHCP pools.
