How to refuse Android 12 update and turn off notifications

[EuLas]

I want to stick with Android 11. I have enabled developer options and disabled Automatic System Updates. However, the download started and I have an in progress notification from DMClient_Downloading that I can't remove (it says "These notifications can't be modified"). What can I do?

Same situation, I would like to know as well. I think it's crazy btw to automatically update to the first version of a new Android release. I managed to stop the download half way. Eventually I ll update, but a few bugfix releases down the road.
