I am in the process of testing Edge Chromium as a Google Chrome replacement. So far I've added a few settings via Group Policy such as homepage, safesearch, and default file associations. I would like the ability to block extensions according to the
below documention this is possible. I've looked through the GPO settings and I don't see ExtensionInstallBlockList anywhere.
