Hello Martin Stelter,
There are a couple of alternatives, one would be connecting to the internet temporarily on another network and downloading the required processor data. Another would be downloading them on a different computer with the Pins Tool and Internet access and exporting the data so that it can be imported on the computer without internet access.
You can see how to do this on the Pins Tool User Guide (link below)
https://www.nxp.com/docs/en/user-guide/IMXPINSGSUG.pdf
If neither of these options are feasible you may open a case requesting this information so that the processor information can be exported and sent to you.
My apologies for the inconvenience. I hope this helps!
Regards,
