Can I configure a fast shutdown?

I am new to ParrotOS and not into programming my OS.
Always when I want to shutdown the computer, a window pops up with a countdown (1minute) and the options to even cancel the shutdown or change into another mode.
Can I change this into direct shutdown without the countdown?
Any suggestion is highly appreciated.

shutdown -h now

Is the command to shutdown without delay. You could look at editing the menu or creating your own button.
