Hello!
Would like to let you know that this issue is relevant for me as well.
I have ThinkPad 14-IIL, ELAN06034 touchpad is not working.
Upgrading the kernel from default 5.4.?? to both 5.6 (linux-oem-20.04) and
5.7.11 (latest available for Ubuntu right now) did not work.
Would love to share
The new kernel 5.7.10 has the ACPI ID for this touchpad added to the
elan-i2c-ids.h. See kernel.org:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/include/linux/input

Just adding the device ID did not fix this problem for me but perhaps
