DNS Configuration Arris TG2472

I am a total neophyte and want help in configuring Pi-hole as my DNS server. What I see in the configuration page of my router does not directly correspond to to the example in the Pi-hole config page: How do I configure my devices to use Pi-hole as their DNS server?.

I have an Arris Touchstone TG2472 router/cable-modem, and the LAN Settings page looks like the image below. To assign Pi-hole as my DNS server, should I: Check the DNS Override box; and then enter my Raspberry Pi IP address in the box for the Primary DNS Server IP? That's my guess, but I'd appreciate confirmation before taking the plunge.

Thanks.

Yes. And leave the other DNS choices empty.

Thank you!
