How do I fix it in place? Do I drill a hole and anchor it with a screw?
This is inside the garage by the way.

Based on the overall condition of this outside corner:
The peeling of the joint compound appears caused by the corner being repeatedly hit.
The corner bead does not appear particularly damaged, deformed, or detached. One could drive a 1-1/4" to 1-1/2" drywall screw through it without pre-drilling (a 10d nail would be sufficient to create a "starter hole", if necessary).
There's not much point in making repairs on this corner unless something is done to prevent further damage (ie. install plastic/rubber baseboard and plastic/metal corner guards).
I've used them before and they do make it a lot easier, especially if you have trouble keeping paper still from moving in the corners, as I do. I don't think they have any structural benefits or anything like that so if you have trouble with paper tape, try them out in a corner and see if it's easier. You can always take it out and go over it with tape if you need to.
