Changing this parameter doesn't result in an outage except in the following case and the change is asynchronously
applied as soon as possible. An outage will result if this parameter is set to <code>true</code> during the
maintenance window, and a newer minor version is available, and Neptune has enabled auto patching for that engine
version.
