Is there a way to stop scrolling?

(Because I used a translator, the words might be weird.)
Hello! Thanks to you, I applied the smooth-scrollbar to ie11.
Thank you!

But there is one problem.
It should not scroll when you mouse-over an element, and it should scroll again when you mouse-out.
Do you have any related options?

I'm using smooth-scrollbar as cdn.
Also I can't use javascript latest grammar because I need to use ie11...

I need an answer, please!
