Walnut Planks Is There A Clearcoat Sealer Which Has No Sheen That Can Be Used Over Painted Finishes?

Is there a clearcoat sealer which has no sheen that can be used over painted finishes? - walnut planks

I make a faux wood grain on the table, walnut flooring line with tung oil .. gloss lacquer finish to speak, but I have my work with a little seal! There must be oil based poly, or maybe the wax, but the lowest gloss satin oil based poly is so shiny and looks. If someone is a coating of tung oil used? I do not know what the results would certainly be regarded as for the wood. Has anyone out there another way, the color white seal ends without adding shine?
Thank you!
