Tested with 2024R2.

Please set the export file path (including file name, without extension) in line 33.
Define a named selection with faces that will be scoped in PT calculator. For this example the named-selection is called ns_faces

# Analysis
modal = Model.Analyses[0]
pt = modal.CreatePostObject("PreTestTreeObject", "NVHToolkit")

# Get faces named selection
ns_type = Ansys.ACT.Automation.Mechanical.NamedSelection
all_face_objs = ExtAPI.DataModel.GetObjectsByName("faces")
ns_faces = filter(lambda x: (x.GetType() == ns_type), all_face_objs)[0]

# Populate PT Tree Object
face_sel = ExtAPI.SelectionManager.CreateSelectionInfo(
    SelectionTypeEnum.GeometryEntities)
face_sel.Ids = ns_faces.Ids
pt.Properties["Geometry/DefineBy/Geo"].Value = face_sel

# Set distance between nodes
pt.Properties["FilterNodesDistance"].Value = 30

# Proximity between sensors
pt.Properties["SensorDefinition"].Properties["ProximityBetweenSensors"].Value = 35

# Set Max Sensors
pt.Properties["SensorDefinition"].Properties["MaximumNumberSensors"].Value = 20
pt.Properties["FilterNodesDistance"].Validate()

# Evaluate
pt.NotifyChange()
modal.Solution.EvaluateAllResults()

# Export UNV File
nvh_tool = ExtAPI.ExtensionManager.GetExtensionByName("NVHToolkit")
# Set sensor and exciter file name including path.
nvh_tool.Attributes["exportdir"] = r"\Path\to\exported\file"
nvh_tool.ScriptScope.PT_PANES["Pre-Test Worksheet"].ExportUNV(pt)
