Could use data modificacion, actions, setTag, with Prometheus pull consumer.

If it's posible to use actions with Prometheus pull consumer class?

You can and should do this on prometheus if you use Prometheus Pull consumer:

https://prometheus.io/docs/prometheus/latest/configuration/configuration/#relabel_config

e.g. extract the name from "[instance]" label, extract the part before the : (regex) create a new target_label with a name you like and as value of the new label (replacement) chose what you extracted from [instance]

e.g.
instance: f5_hostname:443

new_label - value pair:
My_f5_hostname=f5_hostname

metric_relabel_configs:
  - source_labels: [instance]
    separator: "@"
    regex: "([^:]+).*"
    replacement: '${1}'
    target_label: "My_f5_hostname"
    action: "replace"

this is added to all metrics.

I think to add a label there is an much easier way, too.
But I think you have to verify this somewhere in prometheus docs.

static_configs:
  - targets:
    - f5_hostname
        - labels:
          - labelname: value
