Cannot Stop Getting Betas on macOS

Very strange behavior on my macOS recently. I had joined the Apple Developer Beta program for macOS and used the latest 3 beta versions of macOS Big Sur.

Then once Big Sur 11.0.1 (20B29) was released, I promptly removed the profile as described here ("Restore Defaults").

Even after reboots etc., I still get invitation to update to Big Sur 11.1 Beta 11.1

I have tried to download and reinstall the beta enrollment profile and removing it again but had no luck getting rid of it.

Any ideas on how to stop this beta madness?
