Enables KMS v2 to generate single use data encryption keys.
See [Using a KMS Provider for data encryption](/docs/tasks/administer-cluster/kms-provider) for more details.
If the `KMSv2` feature gate is not enabled in your cluster, the value of the `KMSv2KDF` feature gate has no effect.

启用 KMS v2 以生成一次性数据加密密钥。
详情参见[使用 KMS 驱动进行数据加密](/zh-cn/docs/tasks/administer-cluster/kms-provider/)。
如果 `KMSv2` 特性门控在你的集群未被启用，则 `KMSv2KDF` 特性门控的值不会产生任何影响。
