Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge\Cast User Configuration\Administrative Templates\Microsoft Edge\Cast Description
Set this policy to true to show the Cast toolbar icon on the toolbar or the overflow menu. Users won't be able to remove it. If you don't configure this policy or if you disable it, users can pin or remove the icon by using its contextual menu. If you've also set the 'EnableMediaRouter' (Enable Google Cast) policy to false, then this policy is ignored, and the toolbar icon isn't shown.

Enabled: ShowCastIconInToolbar = 1
Disabled: ShowCastIconInToolbar = 0
Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
