When you open a Docker Console for the first time, Token2Shell builds a default container image (token2shell/console) based on Ubuntu OS. And then creates a container from that image and names it "token2shell_root". Whenever you open a Docker Console, this token2shell_root container is started and used for executing your commands (ex. /bin/bash).
Hence, if you want to replace the OS for the Docker Console, you simply need to create a new container with your own OS image and name it token2shell_root.
1. Create your own OS container image
Docker already has many official Linux images. However, they include only minimal set of tools and optimized for running a single app instead of providing a shell prompt. Hence, you should consider building your own image on top of official OS releases.

Please note that in order to access the Docker server installed on Windows from your new container, you must have a "docker" client program. token2shell_root has this binary in /usr/bin. You can copy this to your new container or freshly download it from the official Docker site. When downloading from the official site, please note that you're downloading a full package that also has other daemons and utility binaries; you just need a binary named "docker".
2. Rename containers
Once you have your own container that you want Token2Shell to open as a Docker Console, first rename existing token2shell_root container to "token2shell_root_old" or whatever other name that's not token2shell_root. Then rename your new container to token2shell_root.
3. Stop the original Docker Console container (i.e., token2shell_root_old)
This also will close the connection.
4. Press F5 and reconnect to the Docker Console
Token2Shell should now open your new container instead of the default one.
