/give @p brick{ItemUpgrade:"itemupgrader_core:brick"}
This is the core API for the Item Upgrader mod, adding the feature of Upgrades to the game.
You may be looking for Item Upgrader instead of this, as this has no actual upgrades in it, however this mod is required for the main content mod as it provides all the foundations for the upgrade system.
Upgrades are generally customizable via datapacks/resourcepacks, and you can somewhat easily make your own!
