There do exist several clamps and guiding systems to prevent that. Some are mounted on the printers, some on the spoolholders, and some slide on the edges of the spools.
Long ago I made a slider for my colorFabb spools, after I also had this problem. In fact, I had two problems: originally, some filaments were wound way too stiff on the spool, so it required way too much force to unwind it, it acted like a strong spring resisting unwinding. I had to manually unwind and straighten some filament first. But then it tended to fall off the spool sideways. This slider only worked on spools with a smooth edge that allowed sliding, obviously. So it did not work on older Ultimaker spools, as they had spokes blocking the sliding. I haven't tried it on newer spools.
I would suggest you have a look on Thingiverse and similar sites (I don't know which search terms). Or you can borrow my concept (see picture below), or any other, and adapt it to your requirements. Make sure it slides very smoothly, otherwise if it would get stuck, it would cause failed prints by itself.
I also use this clamp to store spools, and prevent the filament from unwinding or getting tangled up under itself while in storage. In storage I use it with these thumbscrews, and the filament should go through the little hole, to be clamped. For sliding around the edge while printing, obviously no screws should be used, and the filament should not go through the hole. So this is a multi-use thing. Feel free to adapt it to your spools, and test thoroughly: stay with the printer during the first couple of testruns.

S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
