BGP L2VPN EVPN command - import l2vpn evpn * missing

[ITforever]

Hello,

We are configuring L2VPN between N7Ks and cisco ACI. I have just realised that the following command does not exist under BGP af section:

router bgp 5

  neighbor 10.1.1.1

    address-family l2vpn evpn

      l2vpn evpn import stitching-rt re-originate << We don't have this option

According to cisco doc, our version is supporting this command. I am wondering if it requires certain license type or any pre-requisite feature that needs to be enabled beforehand?

Thanks.
