You will need to edit template-tags.php. Back this file up first! If you make a tiny mistake, or I am wrong, your site will not be accessible – at all. This includes the WordPress admin pages. The file is located at /wp-content/themes/nisarg/inc/.
Make sure you can download/upload the files with an SFTP client, or you can edit it with your web host’s portal. You have to be 100% sure you can update this file outside of the WordPress editor. If my recommendation is wrong, or you make a mistake, you need to restore the original file. Again, making a mistake will render your site inaccessible. PROCEED WITH CAUTION!
I looked at this quick, so I may be removing more than what is needed. Perhaps someone else can correct me if I removed too much code.
I commented out the below section to remove the comment count. This is done by adding the “/*” and “*/” to the below code block that already exists in template-tags.php.
/* if(comments_open()){
printf(' <i class="fa fa-comments-o"></i><span class="screen-reader-text">%1$s </span> ',_x( 'Comments', 'Used before post author name.', 'nisarg' ));
comments_popup_link( __('0 Comment','nisarg'), __('1 comment','nisarg'), __('% comments','nisarg'), 'comments-link', '');
} */
