About how to use GPIO of TWR-KM34Z50M

This board drives a liquid crystal, but my application wants to use GPIO without using a liquid crystal. So I'm going to pull out the GPIO signal from the card edge connector of the board, but can I disconnect the LCD?
If it is necessary to disconnect the connection, a zero ohm resistor will be in series with the line, so if I disconnect it, can I disconnect from the LCD?
Looking at the circuit diagram, as an example
Card edge SECONDARY D44 pin: LCD43 / PTC4 has R121.

Thank you.
