Razer Blade 18 (2023): Security error after bios 2.09 update.HELP!!

Good morning Razer Team.

I really need your help with this:

Yesterday i was updating my Razer Blade 18 (2023) and i after the reboot i can see the red,infamous “security” error and after that i can enter in bios and then “Security”-->”Secure boot” and the  voices i can see are these:
- System mode : Deployed
- Vendor Keys : active
- secure boot : enabled  
All these voices are in black but nothing can be selected and/or changed.
So basically i can not do nothing.
I also tried this procedure

but after 5 minutes or more of disconnected coin cell battery and main battery , connecting them again abd re-start the notebook still the same red security error and inside the bios still the same situation of above inside the secure boot screen...So basically i can not do nothing...

Please help and thanks for your patience in advance.
