With the following ARM template, I deploy an Azure Databricks with a custom managed Resource Group Name and add the workers to a custom VNET. In the portal this works fine. But When I try to do this inside an ARM template the managed resource groups keep deploying a workers vnet for the workers. I am thinking that I am on the right track but missing one setting. But can't figure it out. Is there anyone who can see what I am missing ?

You need to nest the vnet in the template, this works for me:
