How to remove timestamp from column name?

Grafana 9.4.7 in docker

My flux query

from(bucket: "zabbix_metrics")
  |> range(start: v.timeRangeStart, stop: v.timeRangeStop)
  |> filter(fn: (r) => r["_measurement"] == "ZabbixWinInventory")
  |> filter(fn: (r) => r["_field"] =~ /^TeamViewer.*/)
  |> pivot(rowKey:["host"], columnKey: ["_field"], valueColumn: "_value")
  |> yield(name: "last")

How to remove timestamp from column name?

I found a solution on how to hide, but when exporting to CSV the time stamp is still there.

Use keep() to keep only the specified columns:

  |> keep(columns:["host", "TeamViewer Version"])
