Hi Jette,
Currently, there is not the option to remove the start date and the only customization options available for the Apple and Google wallet are to add a custom logo, strip image, and background color.I would recommend submitting this as feedback for a future product enhancement request within Participate > Product Ideas.
As an alternative to the Wallet option, you could explore using the plain QR code instead of the passes. You can add the QR widget to emails (ex: confirmation emails, know before you go emails, etc.) and also have it display in the event app if you are using Attendee Hub. How do I create a ticket for my registrants?, Using QR Codes
