A really easy way to remove that nose, although you could argue that it's a sloppy way, is to simply use the claw side of a claw hammer and take some strong whacks into the nose of that 2 by 12 pine. You will quickly see that you can easily remove that overhang without any powertools, and surprisingly accurate too. Once you get a grasp into the grain of the wood, it will break off in a relatively straight line because that's how the grain wants to separate naturally.
It doesn't matter if your edge is not perfectly straight, because that will be 100% covered with your new treads and risers. But if you're getting too rough, you may have to pull out the dust-makers and start sawing.
I do that, but only on the ends after a clean straight cut where the majority of foot traffic is. Your riser board placed on the face, is where the nosing is going to be supported. but I like as much meat as possible especially if they are using 2¼ flooring on the risers as well, instead of solid single painted risers.
