I have the same touchpad issues with the same laptop IdeaPad 5 14ARE05
As requested by You-Sheng, I have added the kernel boot parameters and got some interesting logs.
Although, I am running arch linux, it looks like the journalctl logs are as relevant
Some boot, the touchpad is detected but not fully working (tab click fails, two fingers motion fails, etc)
Otherwise, it is not detected at all.
On kernel 5.7.6:
(no touchpad at all)
i2c_hid i2c-MSFT0004:00: HID over i2c has not been provided an Int IRQ
i2c_hid: probe of i2c-MSFT0004:00 failed with error -22
On kernel 5.8.2-rc2 mainline:

If needed I can attached the full logs, but does not look like there is anything else relevant to this issue.
