Hello, thanks for the script! This technique also works with hwdb like so:

# /etc/udev/hwdb.d/98-latitude-trackpoint-disable.hwdb
# Dell Latitude E7470
# AlpsPS/2 ALPS DualPoint Stick
# udevadm info -a -q all /sys/devices/platform/i8042/serio1/input/input3
evdev:input:b0011v0002p0008e0800-e0,1,2,3,k110,111,112,r0,1,a18,mlsfw
 ID_INPUT=0
 ID_INPUT_MOUSE=0
 ID_INPUT_POINTINGSTICK=0

Afterwards run below to update the hwdb database and reload.

systemd-hwdb update
udevadm trigger

The following udev rule worked for me. You can use wildcards in the device name. The rule is case sensitive, i.e., ATTRS{name} works but ATTRS{NAME} does not.

# ALPS DualPoint Stick: Ignore as input device
ATTRS{name}=="*DualPoint Stick", ENV{ID_INPUT}="", ENV{ID_INPUT_MOUSE}="", ENV{ID_INPUT_POINTINGSTICK}=""
