how to disable player auto-equipping armor/tool/weapon when it breaks?

[. . .]

I find it too cheaty and want to use a mod which disables it, does anybody know a way on how to do it?

I can tell you where you can find them, I don't know how to change them except for using the upvaluehacker as I don't know if the functions can be accessed otherwise.

function fns.OnItemRanOut(inst, data)
    if inst.components.inventory:GetEquippedItem(data.equipslot) == nil then
        local sameTool = inst.components.inventory:FindItem(function(item)
            return item.prefab == data.prefab and
                item.components.equippable ~= nil and
                item.components.equippable.equipslot == data.equipslot
        end)
        if sameTool ~= nil then
            inst.components.inventory:Equip(sameTool)
        end
    end
end

function fns.OnUmbrellaRanOut(inst, data)
    if inst.components.inventory:GetEquippedItem(data.equipslot) == nil then
        local sameTool = inst.components.inventory:FindItem(function(item)
            return item:HasTag("umbrella") and
                item.components.equippable ~= nil and
                item.components.equippable.equipslot == data.equipslot
        end)
        if sameTool ~= nil then
            inst.components.inventory:Equip(sameTool)
        end
    end
end

function fns.ArmorBroke(inst, data)
    if data.armor ~= nil then
        local sameArmor = inst.components.inventory:FindItem(function(item)
            return item.prefab == data.armor.prefab
        end)
        if sameArmor ~= nil then
            inst.components.inventory:Equip(sameArmor)
        end
    end
end
