remove rich snippets from plugin

Hi, I noticed that richsnipped tool by google find many errors and information that is not needed like author’s image, author’s name, date etc. Is it possible to remove it?
I am not good in php; however, I was able to remove:

<div class="comment-author vcard">

                                        <?php echo get_avatar( $comment->comment_author_email, 65 ); ?>

                                        <?php printf( '<span class="author">— %1$s</span>', get_comment_author_link() ); ?>

                                        </div>

from class-woocommerce-product-faqs.php

and this:
echo '<span itemprop="comment" itemscope itemtype="http://schema.org/UserComments"' . link to schema I was able to remove from loop=faqs.php, but some data I just have no clue how to remove:
name and commenttime
I also get an error in richsnippet preview:
“Error: Page contains property “comment” which is not part of the schema.
Error: Page contains property “creator” which is not part of the schema.”

Please let me know what files can I edit and what code to remove.

Reason why I am doing this is google recently stopped showing rich snippets for my products, it doesn’t show price, reviews and stock info in search results, so I decided to do some clean up on that part of the store.
Thanks!!!
