I'm playing without referencing any guides (and I'm just doing some mopping up at this point before I finish the game) so don't take this as gospel, but I don't think they can be turned off. Every time I've encountered a black barrier I've had to find a way around (and I always have so far, with one exception). The barrier in the mushroom section was the first one I found and I didn't find a way around it until much later - I think I needed a new type of movement mechanic to reach an alternate path. Also remember that there are plenty of breakable walls (usually in corners or empty ledges) and sometimes there's a hidden passage when you just press forward without having to break anything.
