Where is the walk only setting?

I need it for Yasuo smooth E dashing. I used to have it on didn't play for months and when I came back something was off. I figured out what However I have looked everywhere and can't find the "Walk only setting"

Is there not walk only setting? Perhaps I used champion attack only to navigate my dashes more precisely over mininos as well as doing camp wall jumps. Idkkkkkkkk Why is there no walk only setting???? Am I blind?
