Manual:$wgDisableQueryPageUpdate

Details
Set this to an array of special page names to prevent  from updating those pages. This setting will be ignored when the script is called with the flag.

Array items can be either in the or in the  format. The run mode is used to show a custom interface message on the special page, instead of the normal "Updates for this page are currently disabled." one. Together with the override flag this can be used to have a default refresh cadence for most query pages but special-case some of them.
