Rust Remove Upgrade Some upgrade

Hello, I am currently looking for a plugin to remove the possibility to upgrade to for example "stone" or "Armoured" using the hammer, to remove it so users are unable to upgrade to anything specified for example if I didn't want them to be able to upgrade to stone I could change "wood" to "Stone" or have "Stone", "wood", and
have both stone and wood un upgradable so multiple blocking.
