If you were just using the default UI bag setup you could

local function Rescale(self)
    self.Count:SetScale(1)
end
 
local function Reset(self)
    self.Count:ClearAllPoints()
    self.Count:SetPoint("BOTTOMRIGHT", 0, 0)
    self.Count:SetFont("Fonts\\arialn.ttf", 13, "OUTLINE")
end
 
for i = 1, NUM_TOTAL_BAG_FRAMES do
    local bag = _G["ContainerFrame" .. i]
    for k, v in pairs(bag.Items) do
        Reset(v)
        Rescale(v)
        hooksecurefunc(v, "SetItemButtonAnchorPoint", Reset)
        hooksecurefunc(v, "SetItemButtonScale", Reset)
 
    end
end

But a bag addon might alter bag/ItemButton configuration so your milage may vary.
