I found the solution: https://askubuntu.com/questions/1248176/ideapad-5-15are05-elan-touchpad-not-working-on-20-04-nor-on-18-04/1257523#1257523

Edit /etc/default/grub and add "initcall_blacklist=elants_i2c_driver_init" to GRUB_CMDLINE_LINUX, run update-grub, power down the laptop and start it again.
