Web Application Firewall (reverse proxy) - block or whitelist public ip addresses

Question

I'm using the WAF as a reverse proxy. I'm wondering if there is a way to block or whitelist access by ip address? 
 
 i found this post from 9 years ago saying it'd be available in 9.3 but if it's available now i'm not seeing it:

Not sure what you mean. 
 You can limit access by 
 
 geoblocking (country or continent based) 
 IP reputation 
 explicitly naming IPs in firewall rules 
 virus scan (uploads only) 
 and firewall profiles, e.g. protocol violations
