Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge\Performance User Configuration\Administrative Templates\Microsoft Edge\Performance Description
Allows efficiency mode to become active when the device is connected to a power source. On devices with no battery, this policy has no effect. If you enable this policy, efficiency mode will become active when the device is connected to a power source. If you disable or don't configure this policy, efficiency mode will never become active when the device is connected to a power source. This policy has no effect if the 'EfficiencyModeEnabled' (Efficiency mode enabled) policy is disabled. Learn more about efficiency mode: https://go.microsoft.com/fwlink/?linkid=2173921

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.
