The system owner can disable transformations on a property or dimension specified by non-system owners. To do this, specify an empty indexingTransforms attribute.

The following example disables transformations by non-system owners on the property named product.color:

"product.color": 
  {
    "ecr:lastModifiedBy": "admin", 
    "propertyDataType": "ALPHA", 
    "indexingTransforms": [], 
    "ecr:type": "property" 
  }
