I think you can stick it just before "return 0" in /etc/rc.d/nfsd.
(I'd probably just go with the "sysctl vfs.newnfs.server_min_nfsvers=4"
 line in this case, since you want it unconditionally?)

Or, if you don't want to build a kernel with "options NFSD", I think
you can get nfsd.ko loaded early by fiddling with loader.conf, but I'm
not volunteering to figure out what works there:-)
