Sometimes EDR agents generate more telemetry than anticipated. There's an option to tune telemetry collection via KEA bases, and in order to do it, telemetry profile, aka "topic-dump", is needed in ready-to-use format.
In order to collect telemetry, do the following:
Please do not run apt-sedr-reset before collecting topic dumps.
Execute the following comma

Problem
If you install standalone Kaspersky Endpoint Agent, both KSC installation package and local installer provide option to choose, which KEA components to install:
However, when KEA is installed in built-in scenario, bundled with KES or KSWS, you don't get to choose and KEA is installed in default configuration, with all the components.
There's a way to select installed KEA components even for built-in scenarios.
Using install_props.json for changing installed comp
