Yes, in this case "xinput --set-prop 10 306 -1.000000"
Default setting was 0.000000 & -1.00000 is the lowest setting it will accept.

I have actually swapped Skywave for Mint 20.2
So I have that plus Zorin OS 16 & Dragon OS Focal.

Zorin is fine default setting, but has a separate acceleration function that can be disabled.
If I could install that on the others it would solve the problem.

Another thing I have found.
The changed setting has stayed in Mint after a restart, but not in Dragon.
