I changed my code like below and it works correctly and I solved my problem.

 var owl2 = $('.owl-gallery');
     owl2.owlCarousel({
      rtl: true,
      margin: 10,
      nav: true,
      loop: false,
      navSpeed: 1000,
      pullDrag: false,
      freeDrag: false,
      autoplay: false,
      onDragged: function () {
         $('body').css('overflow', 'auto');
      },
      onDrag: function (e) {
         var current = e.item.index + 1;
         var  total = e.item.count;
         if (current === total) {
            $('body').css('overflow', 'auto');
         }
         else {
            $('body').css('overflow', 'hidden');
         }

      },
      responsive: {
         0: {
            items: 1
         },
         400: {
            items: 1
         },
         600: {
            items: 1
         },
         900: {
            items: 1
         }

      },
      onTranslate: function () {
         $('.owl-item').find('video').each(function () {
            this.pause();
            this.currentTime = 0;
         });
        
      },
      
   });


owl2.on('drag.owl.carousel', function (e) {
   var current = e.item.index + 1;
   var total = e.item.count;
   document.ontouchmove = function (e) {
      if (current !== total) {
         e.preventDefault();
      }
      else {
         return true;
      }
   }


});


owl2.on('dragged.owl.carousel', function (event) {
   document.ontouchmove = function (e) {
      return true;
   }
});
