To fix my issue, looks like it's running files found in miniconda3/etc/conda/activate.d.There is a file there called oracle-instant-client_activate.sh, which checks for the instant client folder and if it doesn't see it, it downloads the instant client from Oracle's website. I deleted this file and now my problem is gone. There were lots of other files in this directory, too, including env_var.sh, where I decided to set some environment variables.
