how to apply custom-values.yaml on two subchart which is part for main chart

Chart.yaml:-

dependencies:
     - name: prometheus-operator
       version: 8.16.1
       repository: https://kubernetes-charts.storage.googleapis.com/
     - name: fluentd-elasticsearch
       version: 9.4.2
       repository: https://kiwigrid.github.io

Custom-values.yaml

# Change default node-exporter port
prometheus-node-exporter:
  service:
    port: 30206
    targetPort: 30206
prometheus:
  prometheusSpec:
    storageSpec:
       volumeClaimTemplate:
         spec:
           storageClassName: efs
           accessModes: ["ReadWriteOnce"]
           resources:
             requests:
               storage: 5Gi
         selector: {}
elasticsearch:
  hosts: ["https://vpc-logs-abcd:443"]

Running command:-

helm install --namespace dependency test -f /root/custom-values.yaml  /root/customchart

Error/Problem:- Custom-values.yaml is NOT applied on the chart !! Chart Installed with "Default values"

As described here to pass value in subchart you need to define value under dependent chart name section like following

prometheus-operator:
# Change default node-exporter port
  prometheus-node-exporter:
    service:
      port: 30206
      targetPort: 30206
  prometheus:
    prometheusSpec:
      storageSpec:
         volumeClaimTemplate:
           spec:
             storageClassName: efs
             accessModes: ["ReadWriteOnce"]
             resources:
               requests:
                 storage: 5Gi
           selector: {}

fluentd-elasticsearch:
  elasticsearch:
    hosts: ["https://vpc-logs-abcd:443"]

When Helm installs a dependency chart, only the values under the dependency's name are made visible to that chart. When for instance the prometheus-operator chart documentation lists configuration values, those need to be underneath the name of the dependency in your custom-values.yaml.

So your values need to be rearranged to look like:

prometheus-operator: # dependency name from requirements.yaml/chart.yaml
  prometheus:
    prometheusSpec:
      storageSpec: { ... } # as you have it
  prometheus-node-exporter:
    # (Some settings are under nodeExporter; "service" isn't listed
    # in the chart docs)
    ...

fluentd-elasticsearch: # settings for the other dependency
  elasticsearch:
    hosts: ["https://vpc-logs-abcd:443"]
