Edit influxDB Datasource Panel

Hi I wanna create my datasource plugin which gets data from an influxdb server.
I found this guide from grafana tutorials

However this guide assumes that you are building it from the scratch.
What I wanna do is to only edit the UI (User interface) of Query editor in the existing influxDB datasource panel, is there a way to edit datasource panel without doing it from the scratch? I just want to simply edit its interface.

This is the current UI of influxdb query editor:

Thanks and Regards,
