Try this
```
      ValueYaml: !Sub |
        service:
          extraService: |
            HTTP_PORT    2020
```

You can pass custom values to the Helm chart by adding them to the "Values" property in the "fluentbitagent" resource. For example, you can add the following line under the "Values" property:

Values:
  ...
  FluentBitHttpPort: 2020

This will pass the value "2020" for the "FluentBitHttpPort" parameter in the Helm chart. Make sure the parameter is defined in the chart's values.yaml file, otherwise it will not take effect.
