Hi Ghufran,
Thanks for your question.

Simply edit form here dokan/includes/theme-functions.php line 297
function dokan_generate_sync_table() { ...... }
and dokan/includes/order-functions.php line 231
function dokan_sync_insert_order( $order_id ) {.........}

Please hire an expert developer, if you can’t.
Please be aware on next update. You may lose your customize code.

Thank You

Hi Zachary,
You could solve this by adding the following code in dokan->functions.php file

add_filter( 'comment_form_defaults','dokna_remove_comment_hints' );
function dokna_remove_comment_hints( $defaults ) {
$defaults['comment_notes_after'] = '';
return $defaults;
}

Thank you
