OpenVPN two ssid

Hello, I have a scenario in mind that is like this. I have configured the OpenVPN service from nordvpn on my router. Now all my traffic goes through OpenVPN. I want to make two ssid on the router on band 2.4. The traffic of one of the ssid passes through the openvpn service. While other ssid traffic will no longer pass through OpenVPN. How do I do this?
