If you have the time and know-how, you can build your own system off of Ubuntu Base[0]. It's as barebones you can get with Ubuntu - doesn't have snap or any other crap the "minimal" ISO does. You'd need to chroot into it to install the kernel, and you'd probably want to generate an initrd image. I have an example of how to do this on GitHub that you can steal from[1].
