As far as generating a custom config file based on what modules are loaded, you could try "make localmodconfig": It's purpose is described here, https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/plain/README?id=refs/tags/v4.9.9: Create a config based on current config and loaded modules (lsmod). Disables any module option that is not needed for the loaded modules. To generate a custom config for a given architecture, "make defconfig" might be a good way to start. Create a ./.config file by using the default symbol values from either arch/$ARCH/defconfig or arch/$ARCH/configs/${PLATFORM}_defconfig, depending on the architecture. I personally found the Gentoo wiki article that describes the initial kernel configuration as well as which kernel options to set for my nvidia card to be a good foundation to build upon. Hope this makes sense.
