Alertmanager.spec.initContainers.env.valueFrom.secretKeyRef.spec.enableFeatures

enableFeatures defines the Alertmanager's feature flags. By default, no features are enabled. Enabling features which are disabled by default is entirely outside the scope of what the maintainers will support and by doing so, you accept that this behaviour may break at any time without notice. It requires Alertmanager >= 0.27.0.
