The Databricks on AWS docs claim that 30G + 150G EBS drives are mounter to every node by default. But if I use instance type like r5d.2xlarge, it already has local disk so I want to avoid mounting the 150G EBS drive to it. Is there a way to do it?

We usually use instance pools for our jobs, and I tried to create one with disk_spec.disk_count = 0, but it didn't work. The 150G has still been mounted to the machine.
