How to completely disable bootstrap carousel autoscroll?

Question

JavaScript

The site has 2 carousels at the beginning and this code:

$('#panel_1_1').carousel({interval: false});
$('#panel_2_1').carousel({interval: false});

$('.nav-tabs li').on('click', function(){
 $('.tab-panel').carousel({interval: false});
 if( $('.tab-panel').hasClass('active') ){
  var panel_content_id =  $(this).children().attr('href');
  $(panel_content_id).carousel({interval: false});
 }
});

So that the carousel does not scroll by itself and everything seems to be fine, but as soon as you scroll to the next slide, auto scrolling turns on again. How to disable auto scroll?
