How is the Matter DAC pre-provisioning handled, and where is it programmed in the module?
For the pre-provisioned DAC solution, the DAC certificate is programmed into the secure cert partition, and on some chips the DAC private key is programmed into eFuse.
This is handled by Espressif before the chip or module leaves the factory. If you use the pre-provisioned DAC service, customers are generally required to enable both secure boot and flash encryption.
