Is it possible to increase the size of 1 artboard but keep it at the same resolution in Photoshop?

I have created a Photoshop file with multiple artboards in. I need the artboards to be different sizes (in width and height) but was hoping to have a similar pixel size as other artboards that do not need re-sizing. Is it possible to increase the size of 1 artboards, but keep the same amount of pixels as it was before resizing in comparison to other artboards?
