In Windows 10, you can enable and disable Edge extensions in the Local Group Policy Editor. Doing this means non-administrators will not have an option to add any extensions even if they want to. Alternatively, starting in Windows 10 build 14342, you can keep extensions enabled but turn them off instead with a typical toggle you would find in the Settings app.
The following tutorial demonstrates how to turn on/off Microsoft Edge extensions.
