[Network Packet Capture] bpf_filter not available

### Integration Name

Network Packet Capture [network_traffic]

### Dataset Name

_No response_

### Integration Version

1.33.0

### Agent Version

8.17.5

### OS Version and Architecture

Ubuntu 18.04 LTS

### User Goal

The Network Packet Capture integration does not allow for specifying addtional bpf_filter. In the [documentation ](https://www.elastic.co/docs/reference/beats/packetbeat/configuration-interfaces#_bpf_filter)for packetbeat, it's referenced that user can set a bpf_filter for specific network and this is not an option through fleet integrations UI in Kibana.

Packetbeat runs with its automatically generated filter from the integration. This forces agents to process all allowed traffic, which:
* produces excess data
* prevents me from narrowing capturing data to to relevant subnets. I.e multiple packetbeats on a host with different datasets
