helm chart - change default dashboard - disable RSSFeedWidget

[salcinad]

I would like to disable RSSFeedWidget in Kubernetes deployment with helm chart. I was trying to use extraConfig and the DEFAULT_DASHBOARD part from constants.py as values, but ArgoCD is unable to render this.

        extraConfig:
          - values:
              DEFAULT_DASHBOARD: [
                {
                },
            ]

This is the Sync Error from ArgoCD which we get:
one or more objects failed to apply, reason: error when patching "/dev/shm/1852142632": ConfigMap "netbox" is invalid: data[extra-%!s(int=0).yaml]: Invalid value: "extra-%!s(int=0).yaml": a valid config key must consist of alphanumeric characters, '-', '_' or '.' (e.g. 'key.name', or 'KEY_NAME', or 'key-name', regex used for validation is '[-._a-zA-Z0-9]+'),error when patching "/dev/shm/990010489": Deployment.apps "netbox" is invalid: spec.template.spec.containers[0].volumeMounts[4].name: Not found: "extra-config-%!s(int=0)",error when patching "/dev/shm/4005637113": Deployment.apps "netbox-worker" is invalid: spec.template.spec.containers[0].volumeMounts[4].name: Not found: "extra-config-%!s(int=0)",error when patching "/dev/shm/3336613721": CronJob.batch "netbox-housekeeping" is invalid: spec.jobTemplate.spec.template.spec.containers[0].volumeMounts[4].name: Not found: "extra-config-%!s(int=0)"

We are using netbox chart version 5.0.0-beta.154 from artifacthub. Without extraConfig deployment works fine, but as we are in an Airgap environment the RSSFeedWidget does not work and it takes a bit time to get Front Page and we guess it because of that. There was also an Issue with similar problem Issue 12384

If there is any other way to disable RSSFeedWidget we would be glad to test it, currently we did not find and other way.
