I know you can use ConfigMap properties as environment variables in the pod spec, but can you use environment variables declared in the pods spec inside the configmap?

For example:

I have a secret password which I wish to access in my configmap application.properties. The secret looks like so:

apiVersion: v1
data:
  pw: THV3OE9vcXVpYTll==
kind: Secret
metadata:
  name: foo
  namespace: foo-bar
type: Opaque

so inside the pod spec I reference the secret as an env var. The configMap will be mounted as a volume from within the spec:

    env:
      - name: PASSWORD
        valueFrom:
          secretKeyRef:
            name: foo
            key: pw
...

and inside my configMap I can then reference the secret value like so:

apiVersion: v1
kind: ConfigMap
metadata:
  name: application.properties
  namespace: foo-bar
data:
  application.properties: /
    secret.password=$(PASSWORD)

Anything I've found online is just about consuming configMap values as env vars and doesn't mention consuming env vars in configMap values.
