I need to install some open shelving but the brackets they use are at a height that would interfere with the air return pictured. Would it be okay to relocate the return 4” higher or is there a reason (Kentucky code) that dictates how much distance it should be from the ceiling? The ceiling is 9’ high and the air is returned between two studs that are open all the way to top plate. There is no actual ductwork.

If you're not too concerned about aesthetics, you can use some flexible duct (or dryer duct) and a couple boots.
Use some foil HVAC tape to connect one boot to the duct on the ceiling, and then put the other boot on the ground, and use foil tape to connect the boots to the flex duct.
You can get boots that are straight, 45, 90 degrees, and horizontal or vertical, and many sizes -- the box stores all have lots to choose from.
You can also stick a grill on the bottom, just to make it look a very slight amount nicer.
Return ducts are commonly formed using cavities in framing and drywall. The vent opening is often nothing more than a sheet metal frame around which drywall is fit.
Use sheet metal, drywall, and existing framing to create your passage, and simply apply your vent grille where appropriate.

Yes, you can move it up as long as the top plate does not restrict the air flow. I don't know where you are located but where I live there is no code against moving it.
