Important: duplicate posts on the page

Hi, some time ago you sent me a code to avoid duplicate posts on the page (built with WPbakery + Post block).
The code works with all post blocks perfectly.
I have a big problem with blocks with the “load more” button.
Duplicates are displayed.
And I can’t use offset, because I have various blocks in the page, example:
block 1 with categories: ID 1 and ID 2
block 2 with categories: ID 2 and ID 3
block 3 with categories: ID 2, with “load more“.

I can’t set a static offset in block 3, because in block 1 and block 2 there can be from 1 to 10 posts with category ID 2.

can you help me? It is really important to me.
I have worked hard to improve the page and now I am stopped.
Thanks for support

PS. the Code you sent me I think is this:

add_action('parse_query', 'rfischmann__demo_exclude_duplicated_posts');

$newsbeat__posts = array();

function rfischmann__demo_exclude_duplicated_posts( $query ) {
    
    // Bait if is admin side or post type isn't post

    $post_type = $query->get( 'post_type' );

    if( is_admin() || 'post' !== $post_type )
        return;

    global $newsbeat__posts;

    $disable_now = $query->get('newsbeat__disable_edp' ); // use 'disable_edp' to prevent exclusion

    $exclude_posts = $newsbeat__posts;

    if( !$disable_now && !empty( $exclude_posts ) ){
        // We need to respect post ids already in the blacklist.
        $post__not_in = $query->get( 'post__not_in' );

        if ( ! empty( $post__not_in ) ) {
            $exclude_posts = array_merge( (array) $post__not_in, $exclude_posts );
            $exclude_posts = array_unique( $exclude_posts );
        }

        $query->set( 'post__not_in', $exclude_posts );

    }
}

add_filter('the_posts', 'rfischmann__demo_gathered_posts', 10, 2);

function rfischmann__demo_gathered_posts( $posts, $query ) {

    $post_type = $query->get( 'post_type' );
    // Bait if is admin side or post type isn't post
    if( is_admin() || 'post' !== $post_type )
        return $posts;

    global $newsbeat__posts;

    foreach ($posts as $i => $post) {
        $newsbeat__posts[] = $post->ID;

    }

    return $posts;
}
