Allow/Disallow user to change personal data
Merchants who need more control over the checkout flow, particularly for cases where editing information after submission should be restricted, such as B2B closed stores.
Merchants can configure whether edit buttons should be displayed in Contact and Shipping summary components through the admin panel. When the 
hideEditSummary.contact or hideEditSummary.shipping flags are enabled, the corresponding edit buttons will be hidden from the customer view.
Settings
In the Version settings page you can define the behavior of the native summary components.
