 Starting with version 1.11, CSI introduced support for raw block volumes, which
 relies on the raw block volume feature that was introduced in a previous version of
 Kubernetes.  This feature will make it possible for vendors with external CSI drivers to
 implement raw block volumes support in Kubernetes workloads.
 
-CSI block volume support is feature-gated and turned off by default.  To run CSI with
-block volume support enabled, a cluster administrator must enable the feature for each
-Kubernetes component using the following feature gate flags:
-
-```
---feature-gates=BlockVolume=true,CSIBlockVolume=true
-```
+CSI block volume support is feature-gated, but enabled by default. The two
+feature gates which must be enabled for this feature are `BlockVolume` and
+`CSIBlockVolume`.
