vSphere provider from Hashicorp has the very same issue. I am checking this myself and I will try to figure it out.

The issue is that scsi_type must be set to lsilogic-sas, by default is pvscsi. vSphere provider has implemented possibility to change it: https://registry.terraform.io/providers/hashicorp/vsphere/latest/docs/resources/virtual_machine#scsi_type

I'll try to make this a priority. In the mean time, there are ways to use pvscsi (which performs better anyways...). I have not tried it, but you can google it to see how it can be done...
