Anyone else hitting a wall with Vanguard's Secure Boot requirement while trying to pull off an SSD spoof?
Been digging into this for a while, and it is a classic catch-22. If you run a custom driver at StartType 0 to intercept the serial requests before Vanguard initializes, you are forced to disable Secure Boot. But as we all know, Vanguard refuses to launch if Secure Boot is disabled. It is a locked loop.
I have seen people messing around with:
The issue is that once the OS is up, Vanguard has already queried the disk geometry and serials via the disk class driver. You cannot just "fake" it after the fact without a driver that sits at the very bottom of the stack, which immediately triggers the Secure Boot validation check.
Has anyone managed to get a driver to load early enough without tripping the signature enforcement? Or are we strictly looking at needing an EFI-level bypass for the serial hardware reporting? I am starting to think the only way to avoid a perma ban on these accounts is finding a way to pass the Secure Boot check while using a modified bootloader, but that feels like a rabbit hole.
Curious if anyone here has successfully bypassed this check without getting a flag during the game launch. Drop your thoughts below—are you guys sticking to DMA for this, or has someone actually cracked the Vanguard boot-time signature requirement?

I have seen people messing around with:
- Manual Mapping: Injecting the driver later, but the damage is already done because the serials are already cached in the memory by the time you gain execution.
- Signed Driver Exploitation: Trying to use legitimate signed drivers like amifldrv64.sys or others with known vulnerabilities to write/patch memory, but like mentioned, the timing is too late in the boot sequence.
- EFI Bootkits: Theoretically possible to hook the disk IO before Windows even loads, but that is a massive undertaking for a simple HWID bypass and usually triggers an immediate manual ban if the signature check fails.
