Dont be shy or fearful, snoop around at the directories and files. As long as you dont delete, rename or edit & save, then you will do no harm.
With that out of the way, I think you will find most config stuff under /etc. CD into the directory and start listing the file. As you list the directory contents, notice the styling on filenames you see. Chevk for the program name with a .config ending or other styles that you observe. Also, check for the device type or manufacturer. The config file will most likely be a pure text file that you can view, print or edit.
