[Enabling Endpoint Slices](/docs/tasks/administer-cluster/enabling-endpointslices/).
- `GCERegionalPersistentDisk`: Enable the regional PD feature on GCE.
- `GenericEphemeralVolume`: Enables ephemeral, inline volumes that support all features of normal volumes (can be provided by third-party storage vendors, storage capacity tracking, restore from snapshot, etc.). See [Ephemeral Volumes](/docs/concepts/storage/ephemeral-volumes/).
- `GracefulNodeShutdown`: Enables support for graceful shutdown in kubelet. During a system shutdown, kubelet will attempt to detect the shutdown event and gracefully terminate pods running on the node. See [Graceful Node Shutdown](/docs/concepts/architecture/nodes/#graceful-node-shutdown) for more details.
- `HugePages`: Enable the allocation and consumption of pre-allocated [huge pages](/docs/tasks/manage-hugepages/scheduling-hugepages/).
- `HugePageStorageMediumSize`: Enable support for multiple sizes pre-allocated [huge pages](/docs/tasks/manage-hugepages/scheduling-hugepages/).
- `HyperVContainer`: Enable [Hyper-V isolation](https://docs.microsoft.com/en-us/virtualization/windowscontainers/manage-containers/hyperv-container) for Windows containers.
