So don't turn off secure boot. Replace the target machine with an identical decoy machine set up to capture whatever credentials are required to log in to the machine once BitLocker auto-unlocks, then use these to log in to Windows on the original machine and steal any encrypted data accessible by the user who logs in.

This would be more difficult to pull off in the presence of non-password security like a hardware token, as you'd need to forward the actual login UI to the decoy machine, but still not terribly difficult if the login UI will display on an externally-connected monitor and accept input from an externally-connected keyboard and pointing device, and the hardware security device connects via an external interface like USB.

You're now just making up more and more ridiculous nonsense to beat a wrong point.
