Nano rp2040 Connect atecc608a resources

Hello. I am searching for information, sketches, tutorials, etc. that are specific to configuring and using the atecc608a encryption module on the Nano rp2040 connect.

Information I've found predates the rp2040 - this includes:
How IoT device provisioning to the Arduino IoT Cloud works

Arduino Security Primer

This could include secure boot, secure download firmware upgrade (DFU), secure connection to a MKR 1500, etc. Can anyone suggest resources for this? TIA.
