if you look in "systemctl list-unis" you find
prefdm.service loaded active running  Display Manager

so make a one-shot service with the right dependency and enable it
with "systemctl enable yourservice.service "

/etc/systemd/system/yourservice.service
[Unit]
Description=yourservice
Before=prefdm.service
[Service]
Type=oneshot
ExecStart=/path/to/our/script.sh
[Install]
WantedBy=multi-user.target
