Filter read-only dashboards

[sebv004]

Hi,
I'm looking to filter dashboards created by default.
For example, loki helm chart creates configmaps with boards and kube-prom search all namespaces for such kind of configmaps to provision grafana.

I'm very annoyed when I try to pull first and apply with grr.
I get :
FATA[0044] Non-200 response from Grafana while applying dashboard 2xKA_ZK7k: 400 Bad Request {"message":"Cannot save provisioned dashboard"}

Any idea?

Regards,
Seb.
