Description

This policy controls the website compatibility lists that Microsoft provides. The updated website lists are available on Windows Update. If you enable this policy setting, the Microsoft-provided website lists are used during browser navigation. If a user visits a site on the compatibility lists, the pages are automatically displayed in Compatibility View. If you disable this policy setting, the Microsoft-provided website lists are not used. Additionally, the user cannot activate the feature by using the Compatibility View Settings dialog box. If you do not configure this policy setting, the Microsoft-provided website lists are not active. The user can activate the feature by using the Compatibility View Settings dialog box.

These exports write the registry — this is not a managed GPO.
