There is a use case: deploy Prometheus as StatefulSet and config alerting-rules as **ConfigMap**. _alerting-rules_ can take more detail on here: https://prometheus.io/docs/alerting/rules/#alerting-rules it looks like: ```ALERT InstanceMemoryOverload IF node_memory_Active >= 1 FOR 1m LABELS { service = "k8s_metrics", alertname = "InstanceMemoryOverload" } ANNOTATIONS { summary = "Instance {{ $labels.instance }} memory overload", description = "{{ $labels.instance }} memory overload for more than 1 minutes, now is {{ $value }}." } ``` **Can Helm support to ignore {{expr}} which is just for configuration but not render?**
