Summary

It may be the case that one wants to build multiple KERNCONFs in one
buildkernel with some different LOCAL_MODULES options; e.g., build
machine configs likely don't need drm-kmod from ports.

This lets us configure LOCAL_MODULES_DIR_${KERNCONF} and/or
LOCAL_MODULES_${KERNCONF} as needed to override whatever global defaults
may be supplied.

Thank you so much for this. I thought of doing it myself.

Did you try setting LOCAL_MODULES or LOCAL_MODULES_DIR in a kernel config via makeoptions? You can set things like NO_MODULES=yes and MODULES_OVERRIDE in kernel config files via makeoptions.

I was trying to avoid creating a custom config just for that; build machine runs GENERIC-NODEBUG while everything else runs GENERIC or MINIMAL.
