Is it possible with acf to create subpages? for instance if i have a custom post type called “events” that would be at my site address http://www.mysite.com/events/my-event, is there any way to attach sponsors to the page at http://www.mysite.com/events/my-event/sponsors if the sponsors are attached to the event relation-ally?

If you don’t need pretty permalink, you can always use a parameter like this:
This page should give you more idea about it: https://www.advancedcustomfields.com/resources/creating-wp-archive-custom-field-filter/.
I hope this helps 🙂
