So basicly the closest you can get is like this:

local function deleteframe(f)
    if not f.DeletedEvent then
        f.DeletedEvent = f.OnEvent
        f:Hide()
        f.OnEvent = function() end
    end
end
 
local function restoreframe(f)
    if f.DeletedEvent then
        f:Show()
        f.OnEvent = f.DeletedEvent
        f.DeletedEvent  = nil
    end
end
