Dealing with Kindle ebooks in calibre

My Kindles don't receive software updates anymore, so I haven't kept up with the latest. Is there a way for people with newer Kindles to block auto updates?

There is a way as long as the server(s) used for firmware updates are not the same as the server(s) used for downloading eBooks. You could block access to the server(s) that supply the firmware updates.

The hardest part is finding the server(s) to block.

For a non-jailbroken device the only workable method that I am aware of is to fill the storage of the device to the point where there is not enough space remaining to download a firmware update, about 300MB.

But even that is not a guaranteed solution. Amazon has been working on the ability to perform incremental firmware updates, downloading only the files changed since the last release. Those would be too small to be blockable while leaving enough room for the device to function properly.

I was wondering about this. My 11th gen PW is still on 5.18.4 and airplane mode and is not jailbroken. But it's due to have wifi turned back on soon for some KU books I'm ready to swap out.

On the other hand, I still have a K5NT and an Oasis 3 (which so far only goes up to 5.18.2) so I have options.

Thank you @jhowell. Things are certainly looking bleaker and bleaker for Kindle. I will update the first post.

So does a jail broken Kindle allow you to strip the drm given this latest development? Or is it just a way to prevent getting firmware updates? I'm not really clear on how jailbreaking helps dedrm newly published books.
