Per a request on the Hubitat Forums:
I have added ChangeLevel capability into the lzw31-sn, lzw31, lzw42 and lzw41 drivers on my GitHub and have issued a pull request to inovelli’s official github to merge the changes…
The devices supported it already in firmware but there wasn’t a way to utilize it in the drivers.
