"Secure Boot Violation – Invalid signature detected. Check Secure Boot Policy in Setup."

Hello Razer Support,
I have a Razer Blade 14 (2017) with BIOS Version 3.02 (Product Version 6.06).
Whenever I enable Secure Boot, the laptop fails to boot and displays:
"Secure Boot Violation – Invalid signature detected. Check Secure Boot Policy in Setup."
If I disable Secure Boot, Windows boots normally.
I have already performed a clean installation of Windows 10 in UEFI mode and reset the BIOS to default settings, but the issue persists. My BIOS also does not have Key Management or Restore Factory Keys options.
Could you please advise how to restore Secure Boot functionality or whether there is a BIOS update or fix available for my device?
Thank you.
