How to build a full Debian image for the TB-96AI?

I’ve gone around 96boards and I can’t find any way to build a full debian image for this board.

I’ve used the Rock960 in the past and I remember I managed to use a buildsystem stored on gitlab to build both debian and buildroot.

Long story short, I would need to rebuild the kernel for it to add some uncommon modules; is that something possible to be done on this board?

edit: I’m not interested in using Android
