I used to use UICR to store the serial number information during the production with nRF52832.
I am working on new project with nRF9151, but when I check the datasheet, nRF9151 doesn't seem to have a reserved area for custom UICR similar to nRF52832.
Before I give up, I would like to double check if nRF9151 really doesn't have any reserved area for the customers,
If not, any other trick to store this kind of factory information? Should I use NVS instead?
