Interfaces are definitely different and cannot be used with IDispatch, etc.
Someone with more experience might be able to direct you to something, but as far as I know, that’s reserved for C++ (or likely ctypes in python… but that’s on the fringe of what I’m capable of helping with – and completely outside the scope of the pywin32 module). But to make it more clear.. ctypes is how python can call things like that C++ code, but my one endeavor into that space was a VERY long and frustrating road as making sure that all the prerequisite data structures were created (and defined correctly) was a daunting task, and someone ended up figuring it out for me – as I was totally missing different structures that needed to be defined (it was for some data from Terminal Server that is not publicly supported – but totally capable of being read from Windows).

The "application" is basically part of MS Windows. Talking to it via COM is 100% possible, as the C++ code (that is part of the GitHub-Gist) demonstrates<https://gist.github.com/riverar/085d98ffb1343e92225a10817109b2e3#file-quiethours_example-cpp-L23>. It just doesn't work with pywin32. When I look for "6bff4732-81ec-4ffb-ae67-b6c1bc29631f" in the Windows registry, I only find an entry in "HKEY_CLASSES_ROOT\Interface" (there is no entry in HKEY_CLASSES_ROOT\clsid) with a default value of "IQuietHoursSettings". But win32com.client.Dispatch('IQuietHoursSettings') fails with the error message "Invalid class string". Best regards!

Classes are listed in the registry here: HKEY_CLASSES_ROOT\clsid\{6bff4732-81ec-4ffb-ae67-b6c1bc29631f} … and your CLSID would need to exist (as installed from whatever software you are trying to automate) prior to python being able to automate it. Here is an example that should work on your system… ms_dict = win32com.client.Dispatch('Scripting.Dictionary') … because the scripting dictionary object class is installed in just about every Windows OS since pre-WindowsXP I hope this helps.
