That syntax is the correct syntax.
Here's a partial shell script I use for compiling stripped FBSD images
which uses other variables besides __MAKE_CONF should you need examples of
them too:

SRC=/usr/src
POOL=tank
DESTDIR=/jails/templates/13.1-RELEASE
THRDS=`sysctl -n hw.ncpu`
SRCCONF=`pwd`/src.conf
SRC_ENV_CONF=`pwd`/src-env.conf
__MAKE_CONF=`pwd`/make.conf

zfs create -o compression=gzip-9 -o dedup=on -o mountpoint=${DESTDIR}
${POOL}${DESTDIR}
env SRCCONF=$SRCCONF SRC_ENV_CONF=$SRC_ENV_CONF __MAKE_CONF=$__MAKE_CONF
make -C $SRC -j$THRDS world DESTDIR=$DESTDIR
env SRCCONF=$SRCCONF SRC_ENV_CONF=$SRC_ENV_CONF __MAKE_CONF=$__MAKE_CONF
make -C $SRC distribution DESTDIR=$DESTDIR
cp /etc/resolv.conf $DESTDIR/etc/
zfs snapshot ${POOL}${DESTDIR}@initial
