[kube-prometheus-stack] Loading env vars from secrets

Is it possible to set these values using env variables loaded from a secret? I do not see envFrom or extraEnv in prometheusSpec

prometheus:
  prometheusSpec:
    thanos:
      objectStorageConfig:
        secret:
          type: s3
          config:
            bucket: "thanos-objstore"
            endpoint: ""
            region: ""
            access_key: ""
            secret_key: ""

I know we can read everything from a secret using existingsecret but I have my bucketname, endpoint, region in configmap and the aws acces id , key are in a secret. So I felt loading those as env vars would be easier

      #   existingSecret: {}
      #     # name: ""
      #     # key: ""
