Is it possible to change the installation files in the .iso live image of Ubuntu Server, to add a certain kernel configuration option?

My goal is to enable CONFIG_DMA_CMA, so the kernel is compiled with CONFIG_DMA_CMA with every installation from this particular .iso image.

This, of course, depends on whether Ubuntu is actually building the kernel with every installation.

It doesn't matter because your system does not compile the Ubuntu kernel. It is built by Ubuntu and shipped in binary form, as virtually all distributions do. If you need a custom kernel you can follow Ubuntu's directions for building a kernel and making deb packages from it.
