Hi,

The value needs to be set with PowerCfg.

powercfg /setacvalueindex scheme_GUID sub_GUID setting_GUID setting_index

In your case, the sub_GUID is 501a4d13-42af-4429-9fd1-a8218c268e20 and the setting_GUID is ee12f906-d277-404b-b6da-e5fa1a576df5.

The built-in power scheme GUIDs are listed here.

Say you want to set the balanced power plan, run

powercfg /setacvalueindex 381b4222-f694-41f0-9685-ff5bb260df2e 501a4d13-42af-4429-9fd1-a8218c268e20 ee12f906-d277-404b-b6da-e5fa1a576df5 1

Please refer to this link for more details about PowerCfg.
