Possible security problems with using flash on a securebooted device?

Hello,

I am working on a security overhaul before a device hits production.

The device runs MicroPython.

Currently, Secure Boot (v1) is enabled on the device.

The device stores private connection keys as on the flash, that are written to the flash on first boot. I.e. some pseudocode would be ...
