--- Comment #1 from Peter Hutterer <peter.hutterer at who-t.net> ---
libinput doesn't do button mapping, that's handled in the X server. Likewise
with the scroll axis to button emulation.  This "fix" here is like hacking
glibc because you don't want to resolve a specific hostname - less than ideal
and, despite your eye-roll in the debian user forum comment, this is not a bug
in libinput.

The fix would have to be in the server, specifically in
emulate_scroll_button_events() which doesn't appear to take the button mapping
into account.

The main question here though is: why do you need to disable the mouse wheel?
Apparently:

So yeah, nah. Not going to hack libinput for this. Feel free to open a bug
against the X server when you've verified that button mapping isn't taking into
account for scroll button emulation, but don't expect anyone to have the time
to fix this right now. I suggest to get a new mouse, because the amount of
effort required on our side to keep your cat hairs off your wheel is
disproportional to the money a new mouse costs.
