$ oc delete is -l "rhods/buildchain=cuda" -n redhat-ods-applications
$ oc delete bc -l "rhods/buildchain=cuda" -n redhat-ods-applications

Create a new build chain with the patch:

$ oc apply -n redhat-ods-applications -f https://raw.githubusercontent.com/samuelvl/odh-deployer/rhods-3705/jupyterhub/cuda-11.4.2/manifests.yaml
