Respeaker 2-mic - connecting to Up Squared Board

Hello,

I’m using an UP2 (upsquared) Board from AAEON/intel, with R-PI compatible GPIO (already using other Pi-hat boards successfully ).

I’m locked to use Ubuntu 18.04 LTS generic in the following kernel (so no raspbian):
4.15.0-37-generic #40~upboard06-Ubuntu SMP Wed Nov 27 11:29:44 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

And as such I get the following installation errors:
/boot/overlays not found or not a directory
dtparam not found
dtoverlay not found
Errors found, exiting.

Is there any way to install drivers in this setup?
