Perhaps you should take a closer look at what bsdinstall does
when it creates a zfs install pool and boot environment, you
might just find that noatime is already set everywhere but
on /var/mail:
/usr/libexec/bsdinstall/zfsboot:: ${ZFSBOOT_POOL_CREATE_OPTIONS:=-O compress=lz4 -O atime=off}
/usr/libexec/bsdinstall/zfsboot: /var/mail atime=on

Little late... iirc its been that way since day one of zfs support
in bsdinstall.
