how thick is the lumber that is cupped?
Did you mean a “Dewalt” planer or is “Desalt” a name brand too?

You could try putting the concave side up, then shim under the outside edges along the length of the board on both sides to prevent them from flexing down under the pressure from the rollers.

Yes, it’s true a planer won’t make a board flat. It only makes it thinner.
You will need a jointer to make one face flat, and one edge square. Then you can move on to the planner.

If you don’t have access to a jointer there are workarounds like a planer sled, and tons of info exists on that topic.
My preference is to use a jointer for its intended purpose.

Good luck with it.

I do what Brian says, concave side toward the blades and shims along the edge.

You can tape or hot glue shims under the cup.

You can rip the cupped board in half before
planing.

You can remove the cup from one face of the
board using a hand plane.
