+    description:
+      - Optional argument - Set a diskformat for certain uploads like stream optimized VMDKs
+      - There is no official documentation, but it looks like V(StreamVmdk) needs to be set for stream optimized VMDKs that are uploaded to vSAN storage
+      - Setting this for non-VMDK files might lead to undefined behavior and is not supported.
+    choices: ["streamVmdk"]
+    type: str
 
 notes:
   - "This module ought to be run from a system that can access the vCenter or the ESXi directly and has the file to transfer.
