Looking for cap for light bar cutout

I am looking for some type of cap for my 2016+ Tacoma Slimline Hybrid Full Plate Front Bumper by Southern Style Offroad.

I have a 20 inch baja light bar cut out and I don’t really want to get a light bar anytime soon so I’m looking to plug that gap with something. Anyone have a suggestions?

 

a lot of people cover holes like that with mesh from the backside of the hole.

there's custom grille places,

or you can go the home depot route--they've got a few dozen different products that all look about the same, usually in black or silver, though a spray can will make it any color as well.
