So, the best option you have is to not cover junction boxes.

Are electrical junction boxes legal?

Yes any concealed box is a code violation. All splices must be accessable. Now practically speaking if the splice is made properly with wire nuts and the cables properly clamped in the box, you can cover it without concern.

What is code for electrical junction box?

Do junction boxes need a cover?

A: It is important to cover an electrical junction box no matter where it's located. When one or more electrical wires are twisted together, the connection causes resistance to the flow of electricity, which in turn creates heat. With several wires in one box, the heat generated can be multiplied.
