Refresh Map after python script

There has been similar post in the past regarding being able to refresh the map after a python script has run, has there been any updates to this or is there still no solution. The thread below was from 2017, and I have not found a good solution still. There seems to be no resolution to the previous thread about this.

I have had a similar issue with an ArcPy script that is part of an ongoing project. ArcPy script in a Notebook run in ArcGIS Pro. Mine is intended to automate cartographic production; it cycles through calc'ing some fields based on imports from an Excel file, then exporting a layout, wash rinse repeat.

My issue was that not all the layers would draw/refresh in the automated map export. I confirm that the data has actually been updated, and if I refresh the layout manually in Pro, the symbols/labels update per calculated data. But during troubleshooting, often there was a single stubborn layer that would not show up in the automated layout export.

For my first iteration of the script, I was never able to nail down exactly what the issue was, but I defeated it by including an extra map frame, hidden beneath the main map frame, and if that frame was active during the script run, things exported correctly (I know, bizarre 😅).

Incorporating additional functionality into the script now and my old nemesis is back. This is a new thread since I last searched here, so following to see if anyone comes up with any insight on how to force the layout to refresh before exporting it.

UPDATE 6/4/24: Based on some comments made in this post, I came up with a workaround I will be using for this issue going forward. Prior to a single iteration of exporting the map, I (programmatically) remove all the layers from the map, then re-add them from a .lyrx file, then perform the export. Only other adjustment I had to make to the layout was to lock down the extent of all the map frames via constraints (so the basemap layers didn't force the map to zoom to a global extent). Otherwise it is working as the "refresh" I needed for these scripts.
