Razer Blade 15 (2020) - Secure Boot re-enables after shutdown and BIOS date resets

Hello,

I have a Razer Blade 15 Base Model (Early 2020, RZ09-0328) running BIOS version 1.04.

I am experiencing a Secure Boot issue.

After a complete shutdown and power on, Secure Boot automatically re-enables itself and I get the following error:

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

If I enter BIOS, disable Secure Boot, save changes, and restart, Windows boots normally.

However, after a full shutdown, the issue returns again.

I also noticed that the BIOS date resets to 01/01/2020, and Secure Boot becomes enabled again.

Restarting Windows usually works fine, but the problem comes back after the laptop is powered off and turned on again.

Has anyone experienced this issue before?
Could this be related to the RTC/CMOS battery, BIOS settings not being retained, or a BIOS firmware issue?

Thank you.
