  Is it possible to read state of GPIOs 4, 17, 18 of X735 v2.1 by RPi without "script" installed?

  Is any of those GPIOs connected directly to the momentary or latching button connector?

  Hm, I think you can connecting the Raspberry Pi’s general purpose input output ports (GPIO) to a momentary tactile push button switch is a fairly simple circuit. It's connect one side of the switch to an input pin on the Raspberry Pi, in this case use pin 10. The other side of the switch we connect to 3.3V on pin 1 using a resistor. The resistor is used as a current limiting resistor to protect our input pin by limiting the amount of current that can flow. It may be right with your ask. Have a good day!
