should be in man xorg.conf, not sure there's more than that short of google.

the X server's option parsing code is case-insensitive and ignores
underscores. So XkbLayout and xkb_layout are the same option name, which is
why the libinput driver only parses the latter. Not sure where you found
XkbLayout. git grep shows nothing.

Anyway. The drivers only do on-plug xkb option setting, if you have a
desktop environment like GNOME it most likely overwrites the xorg.conf
settings on login.
