--- Comment #1 from Konstantin Belousov <kib@FreeBSD.org> ---
There is ASLR stack gap that randomizes stack location under the limit of
the main thread stack.  You cannot reduce stack size past the gap.

If you so inclined, disable gap with either kern.elf64.aslr.stack_gap set to
zero,
or wait until stable/12 gets the ELF flag to disable stack gap merged.
