try:

$ xinput set-prop "Logitech M325" "libinput Accel Speed" 0.0

and/or then a value up to 1.0 to make it faster.

man 4 libinput has the list of properties and their respective values,
xinput is just a generic tool like cat so its man page won't help you
beyond basic usage information.

You also need to figure out what set the value to -0.4 to begin with.
