I had the same issue (with both Ubuntu 20.04 and 20.10). It does seem to be resolved after installing a 5.9 Kernel with the above patch applied (from @coiby https://www.spinics.net/lists/linux-input/msg69458.html.

I have scripted the process I used (download, patch, compile and install the kernel) for anyone else that's eager to get a working Touchpad on a Ubuntu 20 installation on Lenovo Legion 5 (Obviously there may be unwanted side effects of doing this). This will probably require Secure Boot to be disabled in the BIOS.

See GitHub Gist here: https://gist.github.com/jbuncle/7dacde983b3c33b3b816b10e2fd2308a
Command for convenience: `bash <(curl https://gist.githubusercontent.com/jbuncle/7dacde983b3c33b3b816b10e2fd2308a/raw/build-patched-kernel.sh)`

Note the need for updating GRUB_CMDLINE_LINUX_DEFAULT with i2c-hid.polling_mode=1

(First time I've built the Linux Kernel myself or even commented on here!)
