How to remove a link card cover (preview image)?

Question

I added a card that's just a Google Sheet link. 
I really like that it populates the name of the document but it creates a "preview image" at the top of the card, making the card larger. I don't want that.

How do I remove the auto-generated preview image from the linked card?

Thanks,

@Gaurav Kataria thank you. 
Is there a way to disable the thumbnail for a specific card?
I don't want to disable them for the entire board.

Thanks,

Hi Martin, you can disable the thumbnail preview in the board settings as explained here: https://support.atlassian.com/trello/docs/link-cards/
