Optional Curios Support

[SilverfishStone]

I want to make an item could be a curios item if Curios is present but is worn in an armor slot if not. Is there a way to add optional Curios functionality to a custom item without requiring Curios? For example, the item would allow the wearer to breathe underwater if worn in chest Curios slot, or as a chestplate if curios is not present.

	use inventorytick()
	whit the slot number you can know if its into an armour slot  
	 
	    //########## ########## ##########
    public void inventoryTick(ItemStack helditem, Level warudo, Entity en, int slot, boolean value) {
        Long wtick = 0L;
        int tick = 0;
	        // System.out.println("\n#inventoryTick#\n");
        if( !warudo.isClientSide ){
            wtick = warudo.dayTime();
	            if( wtick % 20 == 0 && en instanceof Player ) {
	                item_handler ih = get_itemhandler(helditem);
	                //inicializar tiempo
                if (ih.start_time < 1L) {
                    ih.start_time = wtick;
                }
	                ih.time = (int) ( wtick - ih.start_time );
                tick = ih.time;
	                //cada 5 seg causar daño por fuego al player
                if (tick > 0 && tick % 100 == 0) {
                    en.setSecondsOnFire(1);
                }
	                //despues de un minuto el lingote se enfria y vielve a ser hierro
                if ( tick > 1200 ) { //
                    helditem = new ItemStack( Items.IRON_INGOT, helditem.getCount() );
                    ((Player) en).getInventory().setItem(slot, helditem );
                }
	            }
        }
    }

I understand how to make the item function in the inventory, but I want to add an optional Curios functionality. Is there a way to add functionality without requiring Curios as a dependency?

that means writing yourself the code
