Hello Remko,

Thank you for reaching out to us.

You can use the following CSS to hide that part of the booking form:

.amelia-app-booking #amelia-booking-wrap #am-events-booking .am-event-list .am-event .am-event-book-cta {
    display:none !important;
}

Hope this works for you.

Please reach out to us if you have any other questions.
