Indeed, yes it does. Just set the corresponding CONFIG_ symbols to 'y'
instead of 'm'. If you don't need to dynamically load any modules
(already have everything you need compiled-in), you can completely
disable module support via disabling CONFIG_MODULES.

For embedded systems, this is quite common. I'm also using it for
trimmed down virtualized workloads that don't ever need to dynamically
load modules.
