Evil DNS + Phishing with evilginx2

I have a pen test lab setup and I want to create my own evil DNS server which will replace the router’s original DNS servers. I want all internet traffic to pass through my evil DNS as usual, but redirect specified sites to my evilginx2 phishing page. How would I go about setting this up?

Here is my current setup:

Evilginx2 running on a Digital Ocean droplet (VPS) and configured my phishing page with a domain from namecheap.com (ex: evilginxphishing.com). Am I able to use my VPS public IP address running evilginx2 as the router’s DNS servers or do I have to build my own DNS server to redirect the router traffic to my evilginx phishing domain (evilginxphishing.com)?
