Vanguard's HWID collection is becoming increasingly intrusive.
While most users focus on raiding their disks and nuking their NIC MACs, the question of Bluetooth adapters is a valid concern for anyone trying to maintain a clean footprint. If you are aiming for a "permanent" spoof, standard software that just flips a registry key or uses a basic driver filter is often insufficient against a kernel-level AC that queries the hardware directly via NDIS or specialized bus requests.
The Firmware Reality
Changing a MAC address at the firmware level (EEPROM) is significantly more complex than a standard BIOS flash. Most consumer-grade USB and PCI Bluetooth adapters use hardcoded identifiers or write-protected memory areas.
Has anyone successfully used vendor-specific flash tools for Intel or Realtek Bluetooth modules to change the hardware MAC, or is everyone just disabling the controller entirely?

- USB Adapters: Typically utilize cheap Realtek or Broadcom controllers. These usually don't have user-accessible firmware interfaces for MAC modification without proprietary vendor tools that are rarely leaked.
- PCI-e / M.2 Modules: If you are running an Intel AX series or similar, you are dealing with a much more sophisticated firmware stack. Attempting to flash these without a hardware programmer is a fast track to bricking the module.
- The Stealth Approach: If you suspect Vanguard is logging your Bluetooth MAC as part of your hardware "blob," the most reliable method isn't spoofing—it's physical removal or a hard disable in the BIOS/UEFI.
VGK is known to scan for unique identifiers across the entire PCIe and USB bus. If your Bluetooth MAC is cached in their database and you only spoof your primary network card, you remain linked. Firmware-level changes are the gold standard, but the barrier to entry is high compared to just swapping a physical card for a few dollars.
