How to delete beta "update is available" after unenrolling from beta? [duplicate]

big-sur beta

I unenrolled from macOS Big Sur beta program, however I am still getting the 11.0.1 "update is available" notification. I would like to remove this so that I upgrade directly to 11.0 when GM is released. I don't want to install 11.0.1. Is there a way to delete cached update data so I only get 11.0 when it's eventually released?

The following Terminal command will stop your Mac from accessing the software update catalog for Beta software:

sudo defaults delete /Library/Preferences/com.apple.SoftwareUpdate CatalogURL

You might need a restart, or relaunch of System Prefs and Command R to reload the Software Update pane at least.
