Hi Aurelio – you could basically try wrapping the code used in that template to display the comment form (normally this is quite simply a line reading comment_form(); ) in a conditional statement, something like this:
if ( ! tribe_is_event_query() ) comment_form();
Does that help here? You might want to make this change in a child theme to prevent your modification from being wiped on a future update – but it would be best to seek the advice of the theme author on that front.
