Hi,
In the current version of ODM on Cloud Rule Designer does not support Big Sur and later. Contact your Devops team, there is a plan to upgrade all cloud instances to the latest release that does support the new Mac OS and they will be able share the schedule.
If you are talking about ODM on Containers (Kubernetes, Cloud Pak for Automation) the latest version ODM 8.11 /CP4BA 21.0.3 does support Mac OS Big Sur.
