Hi,
Yes, it is possible. By default the plugin starts the scroll when the vieport size reaches the average height of 4 items. This number can be changed on the back-end. Setting a very high number, like 1000 will make sure that the scrolling never appears: https://i.imgur.com/AXj29mt.png
You can also turn off the custom scroll script as well, since you won’t be using it: https://i.imgur.com/xz7dh6m.png
I hope this helps!
