While trying to start the services the commands are not giving any feedback and is continuously running, Thus need to terminate it.

did you try:

sudo systemctl restart deskpi-cut-off-power.service

I have just been play with disabling a buck of services, and deskpi-cut-off-power.service is installed & enabled, but was not in the systemd-analyze blame list.

Its likely that power service does not get started until a power-off state (halt, poweroff, reboot) is initiated by SystemD

Yes, that's right, once you initializing the shutdown sequnces, it will trigger the cut-off-power serivce to send "power_off" signal to /dev/ttyUSB0 which is listening by MCU on daughter board, and once the MCU get the "power_off" singal, it will cut off the power, and then, the blue light will turn red on power buttom.
