Hi Gary,
One way that I use is to define an alias in ".bashrc" file for python3 interpreter. If you have a clone python environment point the alias to that python env.
alias python3='C:/Users/asharaf/AppData/Local/ESRI/conda/envs/arcgispro-py3-clone/python.exe'
and then in bash use python3 command.
Let me know if it works in your environment.
