Disabling/controlling shadows?

[Meorge]

In my app, I'd like to have a card view that more closely resembles the Wallet app, where each "card" is more card-shaped and has info show up when selected, instead of each card holding all of the info and taking up a whole screen. To accomplish this, I tried setting the color of the cards to blank, but then their shadows are still visible. Is there a way to disable the shadows so that this doesn't occur?
