Hi Fulton,
Thanks for the inputs and apologies for the delay in response.
to my surprise passing the container prepare in standard worked for me, new
container-prepare is:

parameter_defaults:
  ContainerImagePrepare:
  - push_destination: true
    set:
      ceph_alertmanager_image: alertmanager
      ceph_alertmanager_namespace: quay.ceph.io/prometheus
      ceph_alertmanager_tag: v0.16.2
      ceph_grafana_image: grafana
      ceph_grafana_namespace: quay.ceph.io/app-sre
      ceph_grafana_tag: 6.7.4
      ceph_image: daemon
      ceph_namespace: quay.io/ceph
      ceph_node_exporter_image: node-exporter
      ceph_node_exporter_namespace: quay.ceph.io/prometheus
      ceph_node_exporter_tag: v0.17.0
      ceph_prometheus_image: prometheus
      ceph_prometheus_namespace: quay.ceph.io/prometheus
      ceph_prometheus_tag: v2.7.2
      ceph_tag: v6.0.7-stable-6.0-pacific-centos-stream8
      name_prefix: openstack-
      name_suffix: ''
      namespace: myserver.com:5000/tripleowallaby
      neutron_driver: ovn
      rhel_containers: false
      tag: current-tripleo
    tag_from_label: rdo_version

But if we see or look at these containers I do not see any such containers
available. we have tried looking at Undercloud and overcloud.
Also, the deployment is done when we are passing this config.
Thanks once again.

Also, we need to understand some use cases of using the storage from this
external ceph, which can work as the mount for the VM as direct or Shared
storage. Any idea or available document which tells more about how to
consume external Ceph in the existing triple Overcloud?
Do share in case you know any, please.

Thanks once again for the support, it was really helpful
