Modifying javascript/jquery on wordpress

Hey guys,
I installed a theme that has some desc wrapping effects of some images (when you pass by the image with the mouse cursor, it will slide or something) which is made probably with javascript/jquery?
Is it possibly to deactivate this effect without losing the settings on the next update of my theme? I have created a child theme which I use to edit the css of my website, but I don’t know how should approch jquery/javascript.

ps. I really can’t give you link to the website because it is put on private, but I will try to provide more info if you need to help me solve this problem.

Thanks in advance,
G
