Typically the scroll setting is controlled by Windows - however some devices do overwrite the setting and use their own method.. Touch devices may do this on older versions of Windows - however Windows 10 is very touch friendly... I don't know what you're using so I'll assume Win10... If you're using another, specify here please!
Try editing the setting in Settings > Devices > Mouse > Choose how may lines to scroll each time....
Choose the appropriate device from the list and alter the scrolling method... I'm on a 4k monitor and typically set my scrolling speed anywhere from 8 to 25 - on 1080p I used 3... I only use as low as 8 because some applications have scroll-smoothing which causes issues, or they scroll way too much as they automatically adjust scrolling when most apps don't..
