You cannot change the Kaspersky Scan Engine settings by using the GUI inside a Docker container.
To change the Kaspersky Scan Engine settings in Docker:
docker restart <container ID or name>
You can also restart the container by using the kse_docker_control.sh script, by running sequentially stop_httpd and start_httpd for the HTTP mode, or stop_icapd and start_icapd for the ICAP mode.
