Armour durability?

[Enderwolf]

Hello everyone, so I wanted to know how do I change the Armour Durability on gear?
Would I need a plugin to do this or can you do it somewhere in the spigot config?

There is a way to do it with essentials kits, if you search on the essentials wiki.
and there defiantly is a way to do it with /give (in vanilla minecraft)

/give @p diamond_pickaxe 1 50
