Conditional visibility: Hide Header if no more than 1 item exists in CMS

Hi! I have an event calendar and in the event template under the event description I have “Other Events” header, which displays other events from the CMS, excluding the current one. What I’d like to is to hide this header if there is only one event in the cms. Is it possible? I don’t find any condition like that in the conditional visibility setting.

Thanks in advance.
