I'd like to see specifics though to understand the use case better. What
kind of target you're on, how much space will be saved by only building the
driver you need and which driver is that? If the drivers are in separate
.so objects, you can simply delete the ones you don't need from
do_install_append. The build time savings would be very minimal.
