If the GUI option doesn't show up (which the acceleration option doesn't show up in my mouse settings menu), the terminal command is rather seamless.
From your comment, it appears that your main objective is to reduce the speed of the mouse acceleration. The content of your question also suggests the same.
From the terminal (Ctrl+Alt+t), you can check your current mouse settings with:
$ xset q
Look at the pointer control new the bottom. Change the acceleration to a lower number.
$ xset mouse 4 0
I like my acceleration to be fast so that I don't have to move my hand too much to cover my four monitors. The first number in the command is the acceleration speed. The second number is the threshold.
xset and test the speeds. Set it to one you are comfortable with. You can also fine tune it using fractions.
This will slow your speed substantially:
$ xset 1 0
