Howto disable sidebar on detailed event page

Hi,
I like the eventorganiser plugin, and perhaps want to buy the pro version, because of the booking part of it.
However, i need some help with disabling the sidebar on an event page, and as a result showing the event full width.

I’ve tried some solutions like, disabling the plugin template setting, and copied the 4 templates to the (Child) main theme, and removed the line: <?php get_sidebar(); ?>

but this does not the trick.

I’ve also disabled the events in the sidebar widget, but this does not result in a full width of the event.

e.g.the site, with an example event: https://accscip.nl/agenda/tablet-cafe/

How can i solve this?

Regards,
Sandor
