Is there an offline upgraded version of the Jetour X70 Plus?

I'm sorry, I need more context to provide a translation. Could you please provide more details or sentences for translation?

I haven't seen it before.

It's safer to just buy it at a store, right?

The offline 4S shop did it themselves. I bought the official version.

This is the configuration added by the 4S dealership themselves, claiming it's a special edition, and then they charge extra for it.

If you can't find it online, it's usually customized by the 4S shop. Just go with the ones available online.
