No, this is not possible:

Currently supported install methods include the Anaconda installer and the miniconda installer.

From here

You will either need to install miniconda/anaconda, or use another package manager.

Alternatively, you can use miniforge and its variants, but they still all come "with their own version of python". I don't know of a way to use conda with an existing installation of python
