Hello smz Illinois,
Thank you for using Apple Support Communities. That's an excellent question to ask. If these events are linked to a specific calendar you're set up you, you might be able to remove that calendar from auto-populating events. To do this follow these steps:
On iPhone.
1.) Open the Calendars app.
2.) Tap on Calendars at the bottom of the screen.
3.) De-select the Calendars you wish to no longer appear.
You can also try to manage your Calendar settings:
1.) Go to Settings > Calendars > Siri & Search.
2.) There is a Suggestions section you can edit. This will allow you to disable suggestions that show up in the app.
If these steps fail to resolve your issue, you might need to submit feedback to Apple. Apple does appreciate all feedback regarding their products, services, and features. If you'd like to provide feedback on your experience with their products or services, you can do so using this link: Legal - Unsolicited Idea Submission Policy - Apple
Thank you for using Apple Support Communities. Take care.
