Change active map with python in current project

ArcGIS Pro 2.9.2 on Dell laptop running Windows 10.

I have a project opened and I want to use Python to change the active map. 

For this example, I have two maps in my ArcGISProject. Currently "Map A" is my active map, but when I run some geoprocessing tools, via python window, the output will be added to "Map A", but I want the output to be added to "B Map". 

Can I switch my active map with Python? Or how do I direct the output to a specific map? The arcpy.env does not seem to cover "maps".

import arcpy

aprx ='current')
map1 = aprx.listMaps("Map A")[0]
map2 = aprx.listMaps("B Map")[0]

Thanks for you help.

Is the project open and you are using a notebook or the python window?

tool in arctoolbox

What circumstances would you need to add data to a map that isn't open instead of the one that is?

The project is open, and I am using the Python window.
Use case: In one map I generate a vector tile cache, in another map I process layers and tables for geocoding, routing and other purposes, and in a third map I add the vector tile package, routing network, and other layers and tables from "map2" and output a mobile map package.
Currently I have my scripts divided into 7 "steps" and I manually switch between windows and run the steps. Ideally, I'd like a single script to run the entire process.
I do understand the create vector tile cache and create mobile map package take the map name as an argument, so in theory I could have "map 2" as my active map. However, there is one function that is not exposed in python I must do manually in the vector tile cache "map" before running the create vector tile cache processing. And, I am still learning python to get the AOI layer at the bottom of the layer stack to create the mobile map package, or the extent of the mmpk is incorrect.

Did you ever figure out how to achieve the switch?

I also got stuck trying to do this with arcpy, currently looking into what SDK has to offer for this use case.

within the script I can target which map I add/remove/modify layers. This has help streamline the process. But I still have 3 scripts instead of 7. I still get tripped up in 2 places....

When I am processing layers and I want to add them to the map to output a mobile map package, I can specify the map to add the layers, and then I can turn them off as I don't want them visible, but usable by the app.

# --- gets the current ArcGIS Pro project file

aprx ="CURRENT")

# --- gets the target map

m = aprx.listMaps("MMPK Output*")[0]

# --- sets the path and layers to add

LayerPath = ("D:\\Mobile Map Package Creator\\map_data.gdb\\")


# --- loops thru the layers and adds them to the target map, and then turns the visibility off

for Layer in LayerList:
AddStatus = m.addDataFromPath(LayerPath + Layer)
LayerName = m.listLayers(Layer)[0]
VisibleState = LayerName.visible = 0 #turn off layer


What trips me up?

The extent needs to be entered as a property of the map to create a vector tile cache, I can't find a way to do that in python.

I can't seem to use the above python to add a Network Dataset to the map.
