values not being respect in values.yaml file

We have noticed five instances of incorrect helming in your Kubernetes configuration files. Hardcoded or default configuration values in the template are considered anti-pattern and configurable values in the values.yaml file are not being respect, resulting in user-provided configurations never being applied. Additionally, we provide anecdotal evidence from [trivy-operator#729](https://github.com/aquasecurity/trivy-operator/issues/729) regarding the incorrect helming defect.

This is due to missing implementation for this value in grafana-pod.yaml file:

and elasticsearch-svc.yaml:

## Expected Behavior

These values should take affect when changing them or delete them from values.yaml file

## Actual Behavior

All values mentioned in this issue are not being respect.
