Best way to setup conda init in a specific conda virtualenv?

which is the best way to setup a conda init directly into a specific conda virtualenv within linux (and not the base one)?

I noticed that there is no conda init additional parameter to specify a env.

My attempts to edit ./bashrc were not effective

The original script is

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/opt/conda/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/opt/conda/etc/profile.d/conda.sh" ]; then
        . "/opt/conda/etc/profile.d/conda.sh"
    else
        export PATH="/opt/conda/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<< 

The envs are under /opt/conda/envs/.../bin/

I do not recommend editing the conda initialize code section.

Rather,

1. Disable base auto-activation (once only, not in .bashrc):

   conda config --set auto_activate_base false
   

2. Add activation of the desired environment to the end of .bashrc (or similar):

   conda activate my_env
