Hello cyanic,
Yes there is no PCB files on public website.
If your production is large, you can create a new internal request ( https://support.nxp.com/s/ ) with information:
- your project name and scenarios
- the sufficient reason why you need these data
- the chips ordered yearly.
- company name.
the market will evaluate and make decision if can provide.
