How to add Ingress Gateway certificates, if we install istio using helm chat “istio/gateway” ??

If we go by istioctl, below configuration can be used.

  secretVolumes:
    - mountPath: /etc/istio/ingressgateway-certs
      secretName: istio-ingressgateway-certs
      name: ingressgateway-certs
    - mountPath: /etc/istio/ingressgateway-ca-certs
      secretName: istio-ingressgateway-ca-certs
      name: ingressgateway-ca-certs

Any ideas someone can share…
