2.2. Support overview
Basically, most things work out of the box on this, with FreeBSD 12 and 13 (from Jan 2021).
Exceptions are the LTE modem and fingerprint reader.
Also, there seems to be no support for the tablet sensor, I get nothing when in devd or anywhere when I fold it into tablet position 
USB-C only startet to work with 13 for me, but I did a BIOS update at the same time, so I do not know what actually caused it to work.
I have now switched off Thunderbolt in BIOS, and I can’t remember this setting from before, so it might well be the BIOS.

2.3. Tweaks
Needs acpi_video.ko for brightness control, acpi_ibm.ko does not work for brightness.
For good performance with blender, either start it with
vblank_mode=0 blender
or
LIBGL_DRI3_DISABLE=1 blender
it seems DRI3 is not working, even with the newest i915.ko.
