So basically you don't want the product to exist anymore. Is just (instructing to) archive the page an option? Although now I think of it this will result in a 404.
You could try using the Redirect webpart and enabling it based on the SKUEnabled value. But I think this logic will confuse the customer on why they cant reach the page.
You could also just show a message that the product is no longer available. This way the product is still listed and does the customer know why they cant order.
If you add the following to your transformation:
<%# IfCompare(Eval("SKUEnabled").ToString(), "False", "", "This product is not available.") %>
