No, but you could set it with this procedure:
1. Insert the lines
  vm.kmem_size=123456789
  vm.kmem_size_max=1234567890
in
  /boot/loader.conf

2. reboot

That should change those values...
(see src/sys/kern/kern_malloc.c)

I wonder, why your box needs such a big buffer? Do u have network traffic
bursts or so?
