Bakery default options

Hi,
I ask to Bakery visual composer support but they said to ask you, so…
I use WP_Import to import from an Excel one page for each rows.
The problem is that I want to set the page with this options by Default:
Show Page Heading = OFF
Page Content Top Margin = OFF
Activate Transparent Header = ON
Where I can modify these default options in a new page?
Thank you
