Is there any way I can show/hide the cancel button while using Hosted Vault in an iframe?

I am using the Hosted Vault method in a iframe (https://developer.moneris.com/Documentation/NA/E-Commerce%20Solutions/Hosted%20Solutions/Hosted%20Vault)  and I want to get rid of the Cancel button. I am unable to find anything in the documentation.

It will be a big help if anyone can help me out with it.

 

Thanks.
