Filter input metrics in vmagent (prometheus)

Question

I have vmagent with 1 target. It`s scrape 4k+ samples, but i need about 20. How can I filter unnecessary metrics so as not to store from?

I tried to use this design, but it did not work:

global:
  scrape_interval: 60s
  scrape_timeout: 60s
  external_labels:
    server_name: vmagent

scrape_configs:
  - job_name: "kafka_exporter"
    file_sd_configs:
    - files:
      - kafka_exporter.yml
    params:
      match[]:
        - '{__name__=~"kafka_topic_partitions"}'
