Configurable Product Variation Out of Stock

[AmagArtwork]

I have a configurable product where the variations are simple products. When one of the variations (a simple product) is out of stock, the product page is still showing the buy button. I have enabled stock management and disabled backorders.

Is there a way to turn off the buy button when a variation is out of stock? I'm hoping not to have to purchase an extension.

It is not a default behaviour in Magento so you may have to either customize the code yourself or buy a third party extension.

Is it possible to show all variations even if the parent is marked out of stock?

I'm afraid it's not a default functionality, however it can be done by writing a magento plugin.
