How to enable CHIP_CONFIG_USE_ACCESS_RESTRICTIONS in Matter Config

[Dot2dll]

The Matter stack’s auto-generated file `access_buildconfig.h` explicitly sets `CHIP_CONFIG_USE_ACCESS_RESTRICTIONS` to `0`, overriding my attempts to enable it. This prevents me from enforcing access control in my application. 

Could anyone recommended method to enable CHIP_CONFIG_USE_ACCESS_RESTRICTIONS and similar flags in the nRF Connect SDK? Specifically:

• Is there a Kconfig symbol or build argument to enable this?

• Are there plans to expose these flags in the SDK’s configuration system?

• If manual overrides are required, how can I ensure they persist across clean builds?

Hello,

This prevents me from enforcing access control in my application. 

What form of access control are you after?

I am asking because there are some Matter samples in nRF Connect SDK which has the access control cluster enabled by default, i.e. the light bulb sample. See the usage here in the sample documentation.

Is this what you are after?

Best regards,

Maria
