How to drop enchanted item ?

[HeliumBoi]

So i have this code and it has error, it doesnt drop the item with given enchant protection 1.
and I want the enchant to be hidden too but lmk if you guys know how to do that.

on death of zombie:
    set {_randomvalue} to random number between 1 and 10
    set {_deathvalue} to victim's location
    if {_randomvalue} is less than or equal to 3:
        drop 1 scute named "&bmorganite piece" of protection 1 0.6 meters above {_deathvalue}

So in this code, when you kill a zombie you have 30% chanse to get custom drop(scute). and i want that item to be enchanted so players dont think its normal item.

The best way to modify extra data like enchants/NBT data/ETC is to set the item as a seperate variable THEN enchant the variable/modify it as needed and do with it what you wish (You'll also need the expression "with all flags hidden" or a different one if you plan to set all flags hidden via solely NBT based statements to hide the enchant). I won't give the solution away of how to do this, but check my comment before this. I provided a solution for someone asking how to modify an enchantment on an item which would be a similar enough solution that you could use for this (Check it out here).
