Yes, there is :)

You can set MAKE_JUST_KERNELS:

Thank you! The name is very intuitive, I should have grep-ed for something like this :-)

env MAKE_JUST_KERNELS='yes' make universe

The tunable is a bit `hidden' in the src/Makefile code, near line 292:

292 universe_${target}:
293 .if !defined(MAKE_JUST_KERNELS)
294 @echo ">> ${target} started on `LC_ALL=C date`"
295 -cd ${.CURDIR} && ${MAKE} ${JFLAG} buildworld \
296 TARGET=${target} \
297 __MAKE_CONF=/dev/null \
298 > _.${target}.buildworld 2>&1
299 @echo ">> ${target} buildworld completed on `LC_ALL=C date`"
300 .endif

but it's there already.
