Should I set a page as "No-index" if I include it's content within the front-Page.php via this method?

So I set my home page to "Your latest posts", and included this bit of code to get the info from a pre-defined page so that I can edit my home page, and get access to a "recent posts" grid with pagination at the same time. In addition, I can edit this post via the Gutenberg Block editor with this method.

I'd like to eliminate the possibility of a "duplicate content" flag on my content, so should I no-index the source page?

picture class="featured-image block  pos-rel"
    div class="t-con flex row pos-abs"
        h1  class="post-title f-center" title="?php echo get_the_title( $ID=2 ); ?"?php echo get_the_title( $ID=2 ); ?/h1 !--Edit these values to adjust page being shown.--
    /div
    ?php the_post_thumbnail( 'full', array( 
        'class' = 'featured'
    )); ?
/picture
?php get_search_form(); ?
section class="main bg-darkpurple"
?php 
    $id=2; 
    $post = get_post($id); 
    $content = apply_filters('the_content', $post-post_content); 
    echo $content;  
?

Also, I'm aware that the the_title_attribute() should be used in place of echo get_the_title($ID=2) however, when I use that, even with $ID declared, It outputs the attribute of the latest post instead.

Thanks for the insight!
