how can we disable debug port for nrf5340?

[Jaewook]

Dear Nordic team,

For the security reason to be safe from the hacking, we like to completely disable the debugging and flashing port during production.  

Would you please provide a manufacturing guideline document or any material if available?

Regards,

Jae

By using your manufacturing guideline document, we need to explain it in order to get security approval.
