I have a Dell laptop with "DELL0A78:00 27C6:0D42" touchpad
I have to run
rmmod i2c_hid_acpi && modprobe i2c_hid_acpi for my touchpad to work.
But when i do this, my touchpad loses all its settings which i had set using kde system settings.
the only other issue i have found regarding this problem was in the gentoo forums where OP had to recompile kernel with support for "ASUS TUF fx505dy Touchpad"
heres dmesg with input filter

created a custom systemd service which executes every reboot
it links to an executable which does the following
rmmod i2c_hid_acpi && modprobe i2c_hid_acpi Offline
