A NodePortPassthrough like this

apiVersion: networking.turnbros.app/v1alpha1
kind: NodePortPassthrough
metadata:
  name: nodeportpassthrough-sample
spec:
  labels:
    my-label: label-value
  annotations:
    turnbros.app/service-annotation: annotation-value
  selector:
    app: service-backend
  ports:
    - name: http
      protocols: ["tcp"]
    - name: https
      protocols: ["tcp"]
    - name: game
      protocols: ["tcp", "udp"]

Should produce a Service like this

apiVersion: v1
kind: Service

  name: nodeportpassthrough-sample
  labels:
    foo-label: bar-value
  annotations:
    baz-key: idk-value

    app: service-backend1
  type: NodePort

    - name: http-tcp
      protocol: TCP
      nodePort: 30000
      port: 30000
      
    - name: https-tcp
      protocol: TCP
      nodePort: 30001
      port: 30001
      
    - name: game-tcp
      protocol: TCP
      nodePort: 30002
      port: 30002
      
    - name: game-udp
      protocol: UDP
      nodePort: 30002
      port: 30002
