How can I prevent filebeat from adding a "date.ndjson" to the outputfile I specify ? Is this possible

```auto
output.file:
  path: "/tmp/filebeat"
  filename: filebeat.log

```

```auto
ls /tmp/filebeat/filebeat.log*
/tmp/filebeat/filebeat.log-20250515-1.ndjson  
/tmp/filebeat/filebeat.log-20250515-2.ndjson

```

Is there a way to not append that extension ? I moved from 7.x to 8.x recently and see this change . Earlier it would just create filebeat.log .
