You can get away with relocating it. Take your measurement of the opening you want (include the space required for the drywall as well) then place one bracing 2x4 above and one below.

I like to perform a practical test.

First you cut the stud, then if the roof caves in, you can safely determine that the stud was important.

it isn't that important especially if that is the top floor. if it were at all important it would be located under the ceiling joist not parallel with it. that being said, if you want to make sure that you are ok, you can put up some studs underneath the joist along the adjacent wall which you are not cutting away.

I actually didn’t notice that it was parallel with it, thanks for calling that out. I just assumed it was underneath the joist, and was worried it was carrying load from the floor above.

You're very important, my dude. Don't sell yourself short.

It doesn't look load bearing but it's hard to tell without seeing the full framing of the joists. If you're worried it is you can still add your shelves, just frame it with a 2x6 header to transfer the weight to the side studs like you would a door opening.
