How do I increase head pointer tracking speed more?

I use the macos head pointer on my new M4 MacBook Air, but with pointer speed at 100% it’s still far too slow. I use a 3rd-party device (Quha Zono 2) on my M1 Mac Mini and used Terminal commands to speed this up. They have no effect on the MacBook. LinearMouse also works with the Zono, but won’t recognise the head pointer.

I now think that the head pointer has different settings to the mouse and trackpad. How can I change them either with Terminal or an app?
