Just create a lens profile manually and save it. Google for the proper steps for creating and saving a lens profile.
You might also be able to copy the profile for that lens, if there is one, used, lens mount, for the Leica M series of cameras. It's probably the same lens with a different mount.
The Adobe Lens Profile Creator app is available from midway down this linked page Digital Negative (DNG), Adobe DNG Converter | Adobe Photoshop CC
There's also pdf guide to creating your own profiles.
