Adjust scroll speed

Hello, I can’t find any response so far on this topic. On Gnome (I’m on stable release) I know I can fix the scroll on Firefox with workarounds in about:config but I need a system-wide solution to make bluefin really a daily driver for work. Do you know if is there a way to obtain a slower/less sensitive scroll with two fingers? Maybe changing libinput or the driver settings somewhere?
Thank you in advance!
