Break into Apple HQ. Find out where they have the digital signing servers, then go to that physical location. Break in there, defeat the system security and instruct the system to resign the version of iOS that you want to downgrade to.

Escape. Go home. Downgrade.

You'll need to avoid Apple security and the cops.

Or bribe someone inside Apple to resign your version of iOS.

Otherwise, you can't 'fix' what isn't broken. Apple stops digitally signing older versions of iOS in order to stop exactly the thing you want to do.

You could try to find a used phone that still has the version on it that you want.

Unfortunately, you can't, as Apple has stopped signing iOS 13. It's frustrating because there are many legitimate reasons to want to go back to an earlier version of iOS (bugs, degraded performance, incompatibility with apps, etc). It's quite easy to do on MacOS, and they certainly could make it easy on iOS but just choose not to.

But there also have been quite a few iOS 13 updates since 13.3 as well.

More than that, they actively work to make it difficult.

You can do this if you jailbreak, but you have to have the blobs saved for the version of iOS you want to downgrade to. That was easier to do pre-iOS 6, but Apple changed things in iOS 6 and then added APTicket in iOS 7. Then along came the secure enclave at some point. So now, every duck has to be lined up, the big one (SHSH blobs) before hand.

Stock iOS? No way.

I assume if I got a new iPhone 11 or Pro, it would not have iOS 14 on it ?
It's hard to know. If you got it from Apple, I assume it would have iOS 14. If you got it from some supplier that doesn't turn stock over that quickly, you might still get iOS 13.
