Kubernetes job to update the environment variables in pod

Question

I want to update/inject existing/old environment variables in a pod. How can I do via kubernetes job

This is my daemon set :

apiVersion: apps/v1
kind: DaemonSet
spec:
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      k8s-app: aws-node
  template:
    metadata:
      annotations:
        kubectl.kubernetes.io/restartedAt: "2021-08-30T22:02:00+08:00"
      creationTimestamp: null
      labels:
        k8s-app: aws-node
    spec:
      containers:
      - env:
        - name: DISABLE_METRICS
          value: "false"
        - name: ENABLE_POD_ENI
          value: "false"
        - name: WARM_ENI_TARGET
          value: "1"
        - name: WARM_IP_TARGET
          value: "5"
        name: aws-node
      initContainers:
      - env:
        - name: DISABLE_TCP_EARLY_DEMUX
          value: "false"
        - name: AWS_VPC_K8S_CNI_EXTERNALSNAT
          value: "true"

I want to make ENABLE_POD_ENI as true in main container and add WARM_IP_TARGET as 1 in init container

How can I do that via k8s job
