What the Mendix platform offers is not CICD. You can’t change the “pipelines” because they are not really pipelines.
If you truly need CICD, go with a platform like gitlab/github or any other real pipelining solution. From these pipelines you can deploy to either Mendix cloud ( https://docs.mendix.com/apidocs-mxsdk/apidocs/deploy-api ) or AWS (whatever you prefer here, EC2, ECS, fargate, openshift, etc) depending on your future plans.
If you lack the technical expertise to setup the infra, consider taking a look at https://www.mendix.com/evaluation-guide/app-capabilities/mendix-for-private-cloud/ .
