Disable colorbox link in Image format, for Featured Image.

I would like to prevent the images in each post from being clickable and opening colorbox, as it allows right clicks onto the images for the original size file that I uploaded into my WordPress install.
I love the theme but I want to prevent the above from happening so clients cannot obtain the original size images and print them separately.

I’ve seen suggestions to remove code here and there, but those users didn’t have success with that.

Can there be an option in a subsequent version of Minimatica allowing us to turn off the link, or have the link show a smaller file?
