-> **Note**: When using `mimir-distributed` as a subchart, setting Helm values to `null` requires a workaround due to [a bug in Helm](https://github.com/helm/helm/issues/9027).
-> To set the PodSecurityContext fields to `null`, in addition to the YAML, set the values to `null` via the command line
-> when using `helm`. For example, to use `helm tempalte`:
->
-> ```bash
-> helm template grafana/mimir-distributed -f values.yaml \
->   --set 'mimir-distributed.rbac.podSecurityContext.fsGroup=null' \
->   --set 'mimir-distributed.rbac.podSecurityContext.runAsUser=null' \
->   --set 'mimir-distributed.rbac.podSecurityContext.runAsGroup=null' \
->   --set 'mimir-distributed.rollout_operator.podSecurityContext.fsGroup=null' \
->   --set 'mimir-distributed.rollout_operator.podSecurityContext.runAsUser=null' \
->   --set 'mimir-distributed.rollout_operator.podSecurityContext.runAsGroup=null'
-> ```
