Kibana Not load as HTTPS

i used to helm deployment to deploy the opendistro in my cluster. but i experience an issue that kibana load as http, not https.

Helm chart i used

Value.yaml

i used expose command to expose the port 5601
kubectl expose distro --port 80 --target-port 5601 --type LoadBalancer

based on the values.yml file the ssl is not enabled:

  ssl:
    kibana:
      enabled: false
      existingCertSecret:
      ...
