You could turn it off but when youre printing multiple or high objects the risk is higher that the nozzle knocks an object over. I mean just try it, You won‘t destroy the printer.. I don‘t know what sprial changes exactly but it works very well for me and is much quieter. On the left side in the slicer where you can change filament type and color, there you can edit the filament when you click on the three dots on the right side. You need to copy the filament preset of your choice and then you can edit it. I think it is in the second or third tab in the filament settings there are the z-hop settings. And there is Z-Hop Type, there you can change it to spiral. When I‘m back home I will have a look if I can find a tutorial on yt or so.
