Hi Robin,
Thank you for reaching us out. I am Sherwin from Google Ads API support team. I hope that you are doing well today.
With regard to your concern, based on the error message, you cannot remove the page feed because it is being used by DSA campaign and yes it is by design.
If you have other questions, feel free to reply to this thread.
Kind regards,
