"refactored Nathan's Private DBFS & added conditionals"

[databeaks]

I added a boolean variable in the azure/tf/modules/azure_spoke/variables.tf (default is true) for implementing private dbfs

Fortunately @nathanknox already had the private dbfs terraform code in the Azure SRA folder. I uncommented the azure/tf/modules/azure_spoke/dbfs_privatelink.tf file and added the following conditionals.
Each block in the azure/tf/modules/azure_spoke/dbfs_privatelink.tf will have:

count = var.boolean_create_private_dbfs ? 1 : 0
depends_on = [ azurerm_databricks_workspace.this ]

The first line checks if the variable boolean_create_private_dbfs is set to true (default) or false. Leaving as default or setting to explicit true in the *.tfvars will create all the private dbfs resources as long as the azurerm_databricks_workspace.this dependency is complete.

Looks good, thanks Tony!
