The SSH daemon uses the first value it finds for a given configuration entry if it appears multiple times, so just adding the 00 line below should be enough?

{"/bin/bash", "-c", `test -d /etc/ssh/sshd_config.d && echo -e 'PermitRootLogin=yes\nPasswordAuthentication=yes' > /etc/ssh/sshd_config.d/00-spread.conf`},
{"/bin/bash", "-c", fmt.Sprintf("echo root:'%s' | chpasswd", p.options.Password)},
{"killall", "-HUP", "sshd"},
}
