You cannot perform the removal operation.
You can listen to online radio without any action at: radiosender

@Devyani Rajan Extension for Jira Service Desk allows you to remove "none".

Hi @Devyani Rajan You cannot remove the "none" option from the custom field. 

You can try making the field mandatory and set a default value for that field.
