Razer Blade 15 Base (Early 2021), RZ09-0369AE22. Secure Boot Violation “Invalid signature detected.” Secure Boot disabled allows Windows 11 to boot. Razer's standard securebootrecovery.efi procedure was completed successfully, but the violation returns whenever Secure Boot is enabled. BIOS shows System Mode: Deployed, Vendor Keys: Active, Secure Boot: Enabled. Windows Boot Manager is signed by Windows UEFI CA 2023. Event 1808 reports the 2023 Secure Boot CA/keys were updated, but Windows still reports UEFICA2023Status = InProgress and the Windows UEFI CA 2023 is not detected in the active UEFI db. Please provide the model-specific Secure Boot recovery package or firmware remediation for RZ09-0369.
