Taking which action will automatically enable all severity levels?

In Prisma Cloud, to automatically enable all severity levels for alerts, a user would need to navigate to the Policies section, then to Settings. Within this area, there is an option for "auto-enable default policies," which, when checked for all severity levels, ensures that any default policies related to those severities are automatically activated. This is a configuration setting that streamlines the alerting process by ensuring that all relevant severity levels are covered by the default policies without the need for manual intervention.
