Oh, I have found solution faster than I thought.
I must use acf/save_post but with 20 priority which runs after saving $_POST data.

I’m taking subcategory value from post, checking if that term exist and add it to post using wp_set_post_terms.

Code:

function my_acf_save_post_after($post_id) {

	require_once('wp-load.php' );
	require_once(ABSPATH . 'wp-admin/includes/taxonomy.php');

    // bail early if no ACF data
    if (empty($_POST['acf'])) {
        return;
    }

    //get post value
    $parent_cat2 = get_field('curr_categories', $post_id);
    $test_cat2 = get_field('cat_test', $post_id);

    $term_id = term_exists( $test_cat, 'category', $parent_cat2 );

    wp_set_post_terms( $post_id, $term_id, 'category', true );
}

// run after ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 20);
