I have a free trial for Splunk and am trying to install the Azure Add In to be able to do some testing with Event Hubs and similar however this requires a support case to be raised which I can't do as I don't have an active support contract.
Is there another way I can get the add-in installed?
If you are using "Splunk Cloud" Trail, I guess the answer is NO.
If you want to perform testing for Azure/Event Hub, I would suggest to install "Splunk Enterprise" on your test machine Or create instance on "AWS/Azure". (this will give you flexibility to customize your configuration settings).
