[BUG] Touch-pad is stuck on slow poll rate - Thinkpad P14s Gen 2 (AMD)

[Nolan Provencher]

Good afternoon maintainers! I wanted to report an issue with the 
touchpad on the Thinkpad P14s Gen 2. The touchpad has a delayed feeling 
compared to Windows. Gestures are very hard to trigger on Gnome 
environments on Wayland. I can only trigger gestures if I move my 
fingers very slowly. This issue is persistent and never changes.

[errors]---------

Output from the command 'sudo dmesg | grep synaptic':

[notes] ---------

I have the kernel parameter 'psmouse.synaptics_intertouch=1' set and the 
i2c-hid and hid-rmi kernel modules are not loaded according to the lsmod 
command.
I have also attempted blacklisting the psmouse kernel module in the grub 
configuration as well as creating a blacklist in '/etc/modprobe.d/' 
--but psmouse persists to load regardless.
None of the fix attempts I have tried have resulted in any change in 
symptoms or outcomes.

Thank you for your time!
