I created a script to generated DTM (Digital Terrain Model) from DSM (Digital Surface Model). Github repo in comments.
Indeed it works. I din't even had to change any parameters. Almost identical to groundtruth DTM (Lidar derived). Here is the link - https://github.com/seedlit/dsm2dtm/blob/main/results/example2_dsm2dtm_hillside.png

Large Scale Hydrology: Geocomputational tools that you use
For dem processing, taudem5 has a cli and arcgis toolbox and supposedly supports clusters for large problems. The gdal tools do not have a watershed tool afaik, but handle large datasets well and and can be called from a number of different languages. As others have mentioned, there are many python geoprocessing packages and some work well. I'd second rasterio, the python gdal bindings, and xarray. Pysheds looks interesting but haven't tried.
What are some alternatives?
When comparing dsm2dtm and pysheds you can also consider the following projects:
geemap - A Python package for interactive geospatial analysis and visualization with Google Earth Engine.
whitebox-python - WhiteboxTools Python Frontend
flood-sim - This repo simulates water flooding.
WhiteboxTools-ArcGIS - ArcGIS Python Toolbox for WhiteboxTools
Arda - Maps of J. R. R. Tolkien's Middle Earth using DEM (Digital Elevation Model) and place vectors
gdal - GDAL is an open source MIT licensed translator library for raster and vector geospatial data formats.
