Sagemaker Studio: Local Mode on JupyterLab

Hello, I am following the guide at the link below to set up Local Mode for my JupyterLab application on Sagemaker Studio, but I cannot start Docker. I have enabled Docker Access in the Domain settings and installed Docker in the JupyterLab application but get an error when trying to start Docker with the command sudo service docker start and get a '404 Client Error' when trying to deploy an XGBoost model locally in JupyterLab, although I can deploy the same model to an endpoint in the same application. I believe that it is this issue with Docker which is preventing me from deploying locally but I cannot figure out how to fix it. Thanks in advance for any help!
