Hi Tomas,
You can take a look at the answer from one of my coworker:
It is possible to use the samples without OTA, but the Matter specification states in section "13.5 Firmware" that nodes shall support OTA firmware updates.
If it is only for testing, you can disable OTA by removing the bootloader-related configs from Kconfig.sysbuild, i.e., lines 19-60. You must also modify the pm_static file to remove the MCUboot partitions.

I have found the fully internal partitioning configuration in the Matter Template sample.

docs.nordicsemi.com/.../README.html

I have implemented the internal partitions in my project and it's working!

It would be nice to understand how to turn off the need for a secondary partition, but it's no longer urgent.
