Starting with version 0.99 of the Dash0 Kubernetes Operator, you can define per-namespace settings for exporting telemetry and syncing custom resources (Dash0View, Dash0SyntheticCheck, PrometheusRule, PersesDashboard) to different backends and/or datasets.
The configuration in the Dash0OperatorConfiguration serves as a default that can be overridden by providing an alternative configuration in a namespace's Dash0Monitoring resource.
You can find more details in the operator's documentation.
