Important note: now that we offer dm-verity, the docs should not mention ENABLE_SECURE_BOOT at all
This means getting rid of the first sentences in https://docs.redhat.com/en/documentation/openshift_sandboxed_containers/1.9/html/release_notes/known-issues

There is no need of mentioning secureboot anywhere in CoCo, so please make sure all doc doesn't mention it at all. You can think as if dm-verity replaces secureboot. Enabling it could cause various issues to users.
