You can clean install any Win 10 build you like- all are available for download. However there is probably not now a way to stop it upgrading AND receive updates for that build.

A clean install means deleting all existing partitions created when Windows was installed (but you can keep any data partitions).

You would have no other option than to clean install if you wanted to use an older build, unless you have a disk image created of that build on your PC (We strongly recommend the routine use of disk imaging).

A way that involved using a metered connection then detecting and blocking an upgrade that was proposed is now said not to allow the receipt of updates. However, if you look at the News section, if you were to install, say, build 1511, you could manually download the last available update for 1511 from the thread for that update. (Would take a bit of searching through that section). There is a thread per build per update with manual download links.

You would then have to block updates - which would mean Defender updates too, so you may prefer to use a 3rd party AV.
