Disable/Enable gpio pin

[foomatic]

Hi everyone, just want to preface my question by saying I know zero about how to write a script and I tried googling the answer and couldn't find one clear enough for me to understand.  I have a push button to start my show, and want to disable the button at 9 pm so I can keep my static display up for a few hours without someone pushing the button to start the show . From what I've found, I need a script to disable and enable the gpio pin the button is connected to, but have yet to find this script. I did search this forum and found this topic was discussed briefly but I don't know what to do with the code that was provided:

Any help would be greatly appreciated!
