Self-Hosted Configuration on Docker without bitwarden.sh

I’m thinking of doing a self-hosted installation of Bitwarden, but I’m trying to find out how to install and configure it manually, without using bitwarden.sh.

My particular use case is I have my own infra configuration and I would rather be in control on how each of my docker containers is run vs. having an script that does things magically.

Is it possible? Is there any documentation on a manual installation?
