HKLM\Software\Policies\Microsoft\EdgeUpdate
Minimum number of minutes between automatic update checks. Set this policy to the value 0 to disable all periodic network traffic by Microsoft Edge Update. This is not recommended, as it prevents Microsoft Edge Update itself from receiving stability and security updates. The 'Update policy override default' and per-application 'Update policy override' settings should be used to manage application updates rather than this setting. The values for this policy can range from 0 to 43200.
