Microsoft Edge management service in Microsoft 365 Admin Center lets you set policy and manage users through a Microsoft Edge focused cloud-based management experience. This policy lets you control whether Microsoft Edge management is enabled. If you enable or don't configure this policy, Microsoft Edge will attempt to connect to the Microsoft Edge management service to download and apply policy assigned to the Azure AD account of the user. If you disable this policy, Microsoft Edge will not attempt to connect to the Microsoft Edge management service.
