Module not signed for Ubuntu 16.04 (Clevo P950HR)

Hi,

I have been trying unsuccessfully to install this driver on my Clevo P950HR. However, when calling

 cd module && make && make install

I get the following:

make -C /lib/modules/4.10.0-37-generic/build M=/home/timo/clevo-xsm-wmi/module modules
make[1]: Entering directory '/usr/src/linux-headers-4.10.0-37-generic'

I guess this has to do with the stricter signing that Ubuntu has implemented since 16.04, similar to the problem discussed here: https://github.com/free5lot/hid-apple-patched/issues/23

I tried to follow the instructions to build the kernel module using dkms as described here https://wiki.centos.org/HowTos/BuildingKernelModules, but to no avail. Can anyone help me with this? This particular model of laptop is supported, correct? If its any help, here is some more system info:

Many thanks! Timo
