Re-including list, hope that's okay...

Yes, this is possible. The kernel and the modules can be
found in /usr/obj - the subtree where all parts of the
compiled systems go before they are installed to their
final places. The KODIR variable can be set for the
installation process to _not_ default to /boot/kernel
for the results:
# cd /usr/src
# make kernel KERNCONF=MYKERNEL KODIR=mykernel
NB: "make kernel" is shorthand for "make buildkernel &&
Then you can edit /boot/loader.conf to load your custom
kernel instead of the GENERIC one that's being installed
(and updated with freebsd-update):
This will make the loader load /boot/mykernel/kernel
and ignore /boot/kernel/kernel (the GENERIC kernel).
See "man loader.conf" and /boot/defaults/loader.conf for
details and examples.
Maybe this is helpful:

The loader allows that, too. Its interactive mode can
be used, see the "unload <name>" and "load <name>"
commands when the boot loader has been interrupted.
This assumes you're not using the boot menu.
