Static Routing (Xbox)

Does anyone know if it's possible to add a static route to several different IP Addresses with a Linksys EA7500 Router? By default, all Linksys routers are set to Dynamic Routing, however, I'm trying to block out foreign servers by setting a static route for those IP Addresses. I don't see anything about static routing in the router settings.

This is what I'm looking at inside my router settings: https://prnt.sc/zsf83l (Just a picture)

Side note:

I've tried following this guide: https://www.linksys.com/us/support-article?articleNum=135048 

But the website is outdated!
