You just need too follow the steps shown here:
https://dietpi.com/docs/hardware/#make-your-own-distribution

Simply connect via SSH. There you could execute the conversion script. But you would need to login as user root

If you have a keyboard and monitor connected to your CM4, try <alt>-<ctrl>-<F1> to switch to a console login (w/o X11 GUI).
Maybe also <alt>-<ctrl>-<F2> etc. does it.
