must not disable the keyboard in tablet mode on Thinkpad S1 Yoga (Applies to other TP Yoga models)
Following https://bugs.freedesktop.org/show_bug.cgi?id=106799
When flipped to tablet ThinkPad Yoga S1 locks the keyboard mechanically. Additionally, Super-key on the bottom of the display and volume/rotation lock keys on the side belong to AT Translated Set 2 keyboard, so they are lost of the keyboard is turned off in software.

Currently 90-libinput-model-quirks.hwdb does already that for X1Yoga. it would be sensible to cover all TP yoga models:
# Lenovo Thinkpad X1 Yoga disables the keyboard anyway but has the same device
# use a windows key on the screen and volume rocker on the side (#103749)
