Disable the contactless interface of the card

I have an applet which doesn't work on contactless interface. So my question is if there is any method to disable the contactless interface of the card. If someone can give me any help, I would be much appreciated!

can I have the A40cr with the default keys of the ISD using AES rather than 3DES?
