You can disable specific pages by targeting the name of the page and adding it to the list of items excluded from swipe gestures.
For example, the following code would exclude pages 9 and 21 from swiping.
$(function(){
$('#container').swipe({excludedElements:$.fn.swipe.defaults.excludedElements+=',.page[data-name="9"],.page[data-name="21"]'});
});
Adjust the example as needed.
Note that the string begins with a comma and each page selector is separated with a comma.
This code can be attached as a .js file in the Resources section of the in5 dialog.
