Dremio docker image customization

Iam using the Kubernetes cluster deployment qof dremio where i use helm to get it up and running. Now the issue is that i need to add additional jars of SAP-ASE connectors for experimenting with SAP ASE DB.
How to add SAP-ASE connector jars into my final docker image which can be picked by the helm installer

Iam using the above to do helm install.
So here is what i think can i edit dremio-cloud-tools/Dockerfile at master · dremio/dremio-cloud-tools · GitHub to enhance the Docker file and build it. and push it into my own repository. Will that work ? Please let me know
