Thank you for sharing that link. But it does not explain why override values are not being honoured during install

<@U04MDDLEQQ2> It works as expected.

_override-values.yaml_
```global:
  storageClass: standard  # replace this with your desired storage class
clickhouse:
  cloud: kind
  persistence:
    size: 50Gi
k8-infra:
  presets:
    logsCollection:
      enabled: true
      blacklist:
        enabled: true
        namespaces:
          - platform
          - kube-system```
Helm installation command:
```helm install my-release --create-namespace -n platform signoz/signoz -f override-values.yaml```

<@U04MDDLEQQ2>  It is possible that you had previous signoz installation not removed properly.
Here are proper docs on the same:
