Recently I upgrade to ubuntu 22.04 but when I disable my touchpad in settings, it still works. I didn't have this problem on ubuntu 21.10.
I can disable it by fn+f6
but this isn't permanent. I want to disable it completely not on each startup.

Try to disable the Synaptics touchpad driver, then reboot.
sudo apt remove xserver-xorg-input-synaptics
I had installed the driver to get rid of some erratic behavior due to too high touchpad sensitivity like random text selection etc. However, when I tried to disable the mouse it was not disabled as in your case. Deinstallation helped in my case.
