Computer Configuration\Administrative Templates\Microsoft Edge\Certificate management settings User Configuration\Administrative Templates\Microsoft Edge\Certificate management settings Description
This policy determines the level of access users have when managing CA certificates in Microsoft Edge. Setting the policy to UserOnly (1) allows users to manage only user-imported certificates. Trust settings for built-in certificates cannot be changed. Setting the policy to None (2) lets users view certificates but not manage them. Note: The certificate management experience is available starting in Microsoft Edge version 136. Policy options mapping: * All (0) = Allow users to manage all certificates * UserOnly (1) = Allow users to manage user certificates * None (2) = Disallow users from managing certificates Use the preceding information when configuring this policy.

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.
