ASR 920 12 Port | NAT Settings

[TrivialPants]

I have an ASR 920 | 12 Port with 16.9.2 code that I am attempting to set up NAT on, but I cannot find the commands listed here: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_nat/configuration/xe-16/nat-xe-16-book/iadnat-addr-consv.html

This post below states that is should be available on my router, but I cannot find anything else on it. Does anyone know?
