How can we modify checkout weburl

Hi , 

I like to modify the checkout shipping before clicking on weburl button.

Is there any option to ask shipping address on shopify like  "fieldBaseTypes.required_shipping = false"

so that we can skip shipping address form to fill.
something like this 
`client.checkout.create({ fieldBaseTypes: { requiresShipping: false } }).then((res) => {})`

Please help me.
