No, there is no way built into samba-tool to do what you are asking,
you will have to script something around samba-tool, something like
this:

#!/bin/bash

### Get DNS domain
DNSDOMAIN=$(hostname -d)
# Find DCs FQDN
DCS=$(host -t SRV "_ldap._tcp.${DNSDOMAIN}." | awk '{print $NF}')
# Exit if no DCs found
if [ -z "${DCS}" ]; then
    echo "Could not find an AD DC."
    exit 1
fi
# Use whichever DC is found first
DC=$(echo "$DCS" | head -n 1)
# This removes the trailing dot
DC="${DC::-1}"

echo "Use this DC: $DC"

exit 0
