If you want to manage the Microsoft Edge Chromium browser with VMware Dynamic Environment Manager (DEM), here is a good working template.
Recommended is to deploy the Microsoft Edge Chromium browser for business, which can be found here: https://www.microsoft.com/en-us/edge/business
This DEM config file will capture all important Microsoft Edge settings, but still maintain a relative small .ZIP archive. Although it could still grow, so keep an eye on the filesize.
I have tested with the official 'Roaming Profile support' for Microsoft Edge (https://docs.microsoft.com/en-us/deployedge/microsoft-edge-on-premises-sync) but this is too limited for most customers, since this will miss many important settings like cookies and also requires a (roaming) profile associated with the AD account.
I don't recommended enabling DirectFlex for this application, since this application is so embedded in Windows and many applications depend on it.
How to implement:
Create a new DEM config file using the DEM management console and just copy-paste these lines:
===
# Microsoft Edge Chromium for business
# https://www.microsoft.com/en-us/edge/business
[IncludeRegistryTrees]
HKCU\Software\Microsoft\Edge
[IncludeFiles]
<LocalAppData>\Microsoft\Edge\User Data\First Run
<LocalAppData>\Microsoft\Edge\User Data\Local State
<AppData>\Microsoft\Edge\User Data\Default\profile.pb
[IncludeFolderTrees]
<LocalAppData>\Microsoft\Edge\User Data\Default
[ExcludeFolderTrees]
<LocalAppData>\Microsoft\Edge\User Data\Default\Cache
<LocalAppData>\Microsoft\Edge\User Data\Default\Code Cache
<LocalAppData>\Microsoft\Edge\User Data\Default\GPUCache
<LocalAppData>\Microsoft\Edge\User Data\Default\IndexedDB
<LocalAppData>\Microsoft\Edge\User Data\Default\Service Worker\CacheStorage
<LocalAppData>\Microsoft\Edge\User Data\Default\Service Worker\ScriptCache
===
The end result should look like this:
