Open specific links in same tab and others in new tab

Hi, I added these two custom css scripts to my website. One is for making the images in the carousel slider clickable. The other is for making all external links 'nofollow'. They both have target="_blank" and so the built in toggle switch in squarespace is not changing it. 

But I need to make some links open in a new tab and some (especially the internal ones) open in the same tab.

Will appreciate your advice on this.

The first carousel section with several slides should open in new tab when the toggle switch "open in new tab" is disabled. The other external links set to "open in new tab" should continue doing this.

  $( ( ) => {
  
    const selector = '.user-items-list-carousel__slides .list-item';
    
    $( selector ).each ( function ( ) {
    
      const $this = $( this );
      
      $( $this ).click ( function ( ) {
      
      const url = $( '.list-item-content__button', $this )
      
        .attr ( 'href' );
        
      $( `<a href="${ url }" target="_blank">` )
      
      	.get ( 0 )
        
        .click ( );
        
      } );
      
    } );
    
  } );

  (function () {
    window.addEventListener('load', function () {
      var fixAmazonLinks = function () {
        var amazonLinks = document.querySelectorAll(
          'a[href*="https://"], a[href*="www."]'
        );

        if (!amazonLinks instanceof NodeList) {
          return;
        }

        amazonLinks.forEach(link => {
          link.rel = 'nofollow';
          link.target = '_blank';
        });
      };
      fixAmazonLinks();
    });
  })();
