Remove datePublished and dateModified from Yoast SEO plugin generated Article schema

I’m trying to remove date properties from Article schema generated by the Yoast SEO plugin.

In their developer docs the wpseo_schema_article filter is set as an example for manipulating with Article graph piece. However even with this type="application/ld+json":

<script type="application/ld+json">
{
   "@context":"https://schema.org",
   "@type":"Article",
   "mainEntityOfPage":{
      "@type":"WebPage",
      "@id":"https://www.myproscooter.com/etwow-electric-scooters-review/"
   },
   "headline":"E-Twow Electric Scooters 2021 Review",
   "image":{
      "@type":"ImageObject",
      "url":"https://www.myproscooter.com/wp-content/uploads/2020/12/elek-scoot.jpg",
      "width":700,
      "height":400
   },
   "datePublished":"2020-12-08T08:52:13",
   "dateModified":"2021-01-12T11:30:10",
   "author":{
      "@type":"Person",
      "name":"Jason"
   },
   "publisher":{
      "@type":"Organization",
      "name":"MyProScooter",
      "logo":{
         "@type":"ImageObject",
         "url":"https://www.myproscooter.com/wp-content/uploads/2021/01/MPS-Logo-228x60.png"
      }
   }
}
</script>

When I try to access and manipulate data like this:

add_filter( 'wpseo_schema_article', 'remove_article_dates' );


function remove_article_dates( $data ) {

    file_put_contents(WP_CONTENT_DIR.'/helper-seo.txt','DATA PRE FILTER: '.print_r($data,true),FILE_APPEND);

    unset($data['datePublished']);
    unset($data['dateModified']);

    return $data;
}

Nothing gets logged into helper-seo.txt nor do dates get unset in the Article schema; as if the filter is ignored totally.

What’s more confusing is that manipulation with dates in Webpage Schema works and is similar to the above:

add_filter( 'wpseo_schema_webpage', 'remove_webpage_dates');

function remove_webpage_dates( $data ) {

    unset($data['datePublished']);
    unset($data['dateModified']);

    return $data;
}

The other stuff I’ve tried include:

add_filter( 'wpseo_schema_article_date_published', '__return_false' );

add_filter( 'wpseo_schema_article_date_modified', '__return_false' );

Which isn’t reflecting into Article schema at all. How to remove these properties sucessfully?

    add_filter ( 'wpseo_schema_webpage' , 'remove_breadcrumbs_property_from_webpage' , 11 , 1 ) ;
function remove_breadcrumbs_property_from_webpage( $data ) {
    if (array_key_exists('datePublished', $data)) {

    Try this exact code. I’m sure it will work for you. This cleared my problems at least.

    // Remove DatePublished
add_filter( 'wpseo_schema_graph_pieces', 'remove_datePublished_from_schema', 11, 2 );
add_filter( 'wpseo_schema_webpage', 'remove_datePublished_property_from_webpage', 11, 1 );

/**
 * Removes the DatePublished graph pieces from the schema collector.
 *
 * @param array  $pieces  The current graph pieces.
 * @param string $context The current context.
 *
 * @return array The remaining graph pieces.
 */
function remove_datePublished_from_schema( $pieces, $context ) {
    return array_filter( $pieces, function( $piece ) {
        return ! $piece instanceof YoastWPSEOGeneratorsSchemadatePublished;
    } );
}

/**
 * Removes the DatePublished property from the WebPage piece.
 *
 * @param array $data The WebPage's properties.
 *
 * @return array The modified WebPage properties.
 */
function remove_datePublished_property_from_webpage( $data ) {
    if (array_key_exists('datePublished', $data)) {
        unset($data['datePublished']);
    }
    return $data;
}

    None of those solutions worked for me, and I finally had to modify the Yoast plugin file wordpress-seosrcpresentersopen-grapharticle-modified-time-presenter.php and change line 32 return $this->presentation->open_graph_article_modified_time; to this instead return null; and yes I realize that’ll get overwritten by future plugin updates.
