Increase code size region to 1 MB programmatically or a script

Hi,

I am using WiRA SDK 10.440.8.6. My firmware is above 512KB and the following link helps to configure the Dialog to increase the code size partition to 1 MB from a 512KB.

How do we handle this in production? Can we write this into the firmware code itself so that when we flash the firwmare, we can set the CACHE register to 0x5 and the code size is increases to 1 MB?

Or is there any script that can be executed on the Windows before I flash firmware which will do this instead of using Smartsnippets Toolbox and going through the UI to configure to 1 MB code size ?

Thanks and Regards,
