No need to hide the link. map it into an obscure dev menu item and simply add a no-index no-follow value on its metadata.
This is a temp menu item which you can discard afterwards.

You learn something new every day: cineaulac.ch/index.php?option=com_content&view=featured
For some reason only two of the six K2 items are showing, but that should be enough to give you an idea...
Many thanks, Krikor!

Thanks Krikor, I've found anther way to show those items for now. Haven't been able to pinpoint the issue with the K2 images, though. The link above doesn't work anymore, but I'll come back if I find another issue that I could pick your brains about. Thanks!

Sure :) I 'll be happy to help.
