Issue

• Kernel module fails to load due to Secure Boot being enabled and the module not being correctly signed.
• Need to add a new key to the MOK database in Red Hat CoreOS.
• Enroll the new key through the MOK Manager UI in Google Cloud Platform (GCP).
• Unable to load and consume 3rd party kernel modules due to this issue.
