Secure Boot Option Greyed out in Surface 3 BIOS

I am trying to Dual Boot/Install Parrot OS on my Surface and i need to disable secure boot.

This is the issue in step form:

1: I access the bios password screen and Press "ENTER" (Without entering a Password) and access the BIOS interface. (Note. NOT the UEFI)

2: I go to select Secure Boot, but i can only access Device Information as all other options are unavailable.

I do not know how to enable the BIOS Options and have searched endlessly to no avail.

Hope you can help.

UEFI Secure Boot - Greyed out - Disabled

Hi Alistair,

I am Dave, I will help you with this.

When booting from a USB, Secure Boot should be disabled, not enabled.

Is there a CSM setting in your BIOS, if there is, disable that permanently, ensure secure boot is disabled, then set the USB as the primary boot device, save those settings and you should be able to boot form the USB.
