Hi,
We don't have default options for that, you will have to create a plugin based on the function "onAfterProductQuantityCheck()" in order to check if:
if( $displayErrors && $wantedQuantity > $quantity )
If you are in this if condition, so you can add session data to tell that this product can no more be added to cart.

Then edit the view "product / quantity" and check in the session the data for the current product, if it can't be added to cart so edit the button to display a greyed one without any actions onclick, or simply hide the button.
