We already have a couple of DTs for laptops where the touchscreen may
be there or not, with the additional hid-over-i2c node defined
unconditionally and it works out fine

For the panel, it depends.. If it's another "Samsung ATNA"-class panel
(which I would guess is the case, but can't know for sure), and there's
no other changes, then it would work too.

I opened the build configurator on the Lenovo website and I can order
both kinds of panels with both kinds of SoCs (X2 Plus / Elite)

I unfortunately don't know the answer to that question.. 

They all carry the same model number on the website, it seems

Should we go forward with an optimistic, single compatible for the known
variant ("lenovo,yoga-slim7x-gen11", "qcom,glymur") then?
