To disable automatic updates for all system-defined boot sources, turn off the `enableCommonBootImageImport`feature gate by setting the value to `false`. Setting this value to `true` re-enables the feature gate and turns automatic updates back on.

You can opt out of automatic updates for all system-defined boot sources by disabling the `enableCommonBootImageImport` feature gate. If you disable this feature gate, all `DataImportCron` objects are deleted.

When the `enableCommonBootImageImport` feature gate is disabled, `DataSource` objects are reset so that they no longer point to the original boot source. An administrator can manually provide a boot source by creating a new persistent volume claim (PVC) or volume snapshot for the `DataSource` object, then populating it with an operating system image.

You must configure a storage class. Otherwise, the cluster cannot receive automated updates for custom boot sources. See xref:../../storage/dynamic-provisioning.adoc#defining-storage-classes_dynamic-provisioning[Defining a storage class] for details.
