Is it possible to have passkey with Just Works bonding

[Renix]

I noticed some suggestions to add Static Passkey.

I have 10040 nrf52832 sdk13.0.0 s132

The server has no IO, so cannot enter passkey from it.

1. Is there an example to add PIN to the server, even though Just Works is used?

2. How would one update / set this passkey at production time. or

3. How would one update / set this passkey in the field, during deployment.

Can I add

Any help appreciated.
