I think there is some work being done in grafana/helm-charts#2481 (it seems to me mimir uses this GH workflow for helm releases).

Hey, I opened the issue here, because the helm chart was moved over here (https://github.com/grafana/helm-charts/tree/main/charts/mimir-distributed)

Sure, thank you for the issue. What I've noted above is that mimir's CI workflow, which releases the chart, keeps using the workflow that lives in grafana/helm-charts. After they resolve grafana/helm-charts#2481 I expect mimir to get the feature automatically.

Update: there is grafana/helm-charts#3068 now
