Sure the huion guys won’t tell you to use wacom commands to configure their product. But it works with my huion q11k v1.
There is no file to adapt, those are command lines you repeat every time you log in your session or plug in the tablet. So you want to make a script and assign it a shortcut so you can execute it quickly everytime you need. I did this to change monitors for example, it works well.
I’ve done it on Linux mint, no idea for non ubuntu based distros.
