How to disable blur outside of slide?

I'm not sure that's the correct terminology, so let me expand... When you're on edit mode, you can insert objects and if you move it outside of the slide (that is, outside of the edges, "past the border limits" so to speak), it blurs or darkens, so you concentrate on the slide itself.

I need to make an e-learning script (which I always do in PowerPoint) and need to add annotations for the editors on the edges of the slide (for example, to explain if the slide does something in particular) and other text boxes (for pop ups that should be designed), but the blur doesn't let me work properly because I can't see what I'm writing or where the object is (well, slightly).

No, I can't take my work computer home. I already have my own (the Mac) in which I want to work in (and export to .pptx when done).

Is there a way to disable this blur?
