“is it possible to not download the updates”
For Win 10, 11?
Not sure about that. When MS was still supporting Win 7 I set it to not do auto updates — just to be prompted.
Years later I still get the notice that update at available. It’s a trick. I think Fauci is behind it.
For Win 10, 11?
Yes, there are ways to turn off the automatic updates in Windows 10 and 11. My post 43 in this thread covers just one of the methods.
