Pre-installed Extensions

Is it possible to pre-install to extensions like described here for Chromium: https://www.chromium.org/administrators/pre-installed-extensions

Background: We want to force the installation of a CRX extension hosted locally (on a file share [UNC]) on domain-joined devices. According to https://docs.microsoft.com/en-us/DeployEdge/microsoft-edge-policies#extensioninstallforcelist : For Windows devices that aren't joined to a Microsoft Active Directory domain, forced installation is limited to extensions available in the Microsoft Store. But we don't want to use the store as this is an extension only used within our enterprise.
