Script Tool, Print Selected Features

[aecho2]

Need help printing only selected features in a layer, currently have the following:

import arcpy

#Set variables
arcpy.mp.ArcGISProject('CURRENT')
aprx = arcpy.mp.ArcGISProject('CURRENT')
TCG4232_USNG_GRIDS = "P:/PROJECTS/RP_Quality_Control_cGIS/MapSalesArcProProject/MapSalesLive1211/MapSalesLive/Data/GRIDS/USNG_GRID_OH.gdb"
Output_Folder = arcpy.GetParameterAsText(0)

#list of layer names that you want to be turned off.
p = arcpy.mp.ArcGISProject("Current")
m = p.listMaps("Map")[0]
layer_names = ['TCG4232_USNG_GRIDS']
lyrList = m.listLayers()
for lyr in lyrList:
    lyr.visible = True
    if lyr.name in layer_names:
        lyr.visible = False

#Print to PDF
try:
    aprx = arcpy.mp.ArcGISProject('CURRENT')
    l = aprx.listLayouts()[0]
    l.mapSeries.refresh()

    if l.mapSeries is not None:
        ms = l.mapSeries
        if ms.enabled:
            ms = l.mapSeries
            indexLyr = "TCG4232_USNG_GRIDS"
            ms.exportToPDF(Output_Folder,"SELECTED",
                "",
                "PDF_SINGLE_FILE",
                150,
                "FASTEST",
                True,
                "ADAPTIVE",
                True,
                "LAYERS_ONLY",
                True,
                80,
                True,
                False)
except Exception as e:
    print(f"Error: {e.args[0]}")

the lyr.visible turns the layer on/off only (either view all or none).

If you want to just display a subset of the data in a layer, you would put a definition query on the layer and have that layer as visible = True.

I Intended to turn off the layer, my print needs the layer off but I still need the region of the layer area to print. 

I just need my print to target the "TCG4232_Grids" layer.
