Grafana Loki gateway service type as NodePort

Hi team, I’m trying to set up Grafana Loki and need the gateway service to be created as a NodePort. I’m using this values configuration but the service is still ClusterIP. Am I missing any configuration?

gateway:
  autoscaling:
    enabled: true
    maxReplicas: 3
    minReplicas: 1
  replicas: 2
  service:
    annotations:
      alb.ingress.kubernetes.io/success-codes: 200-399
    type: NodePort
    nodePort: 8080
    port: 80

Thanks
