Clarke Rubber sell a variety of grommets and plugs, or you could go full race car spec and use a couple of pieces of aluminium tape on either side of the hole. This is how i've covered alot of redundant holes in my car. You can even paint the tape to match the body colour.

Computer case motherboard grommets may even work. They come in a variety of sizes.
I made some holes in my old PC case for cable management.
All you need is the size, then start looking.
