Computer Configuration\Administrative Templates\Windows Components\Microsoft Edge User Configuration\Administrative Templates\Windows Components\Microsoft Edge Description
With this policy, you can specify whether to allow full-screen mode, which shows only the web content and hides the Microsoft Edge UI. If enabled or not configured, full-screen mode is available for use in Microsoft Edge. Your users and extensions must have the proper permissions. If disabled, full-screen mode is unavailable for use in Microsoft Edge.

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.
