Looking into the values file here:
https://github.com/dapr/dashboard/blob/master/chart/dapr-dashboard/values.yaml
And chart options here:
https://github.com/dapr/dashboard/tree/master/chart/dapr-dashboard#chart-options
I tried setting ha.enabled to true in the helm chart and nothing changed, there was still only 1 replica of the dashboard. But then I noticed there's replicaCount at the top level that I set to 3 and I got 3 replicas.
Maybe the ha.enabled part was copied when moving from the main chart, but doesn't do anything and should be removed?
