Is there a way to disable auto-run in Fortnite on iOS?

Since the Season 4 update, the auto-run feature can be enabled by holding down and dragging the left movement control. Personally, this has caused a few accidents, like when I’m trying to silently crawl around and I suddenly break out into a full on sprint… blowing my cover.. and of course becoming someone else’s easy kill.

Anyone know if this can be disabled? I couldn’t find it in the settings. Thanks.
