That doesn’t help. If they have physical access they can make the system boot into a fake login screen and capture your password.
Securing the bios is necessary.
If someone has that much physical access to your machine they can capture your password far more easily with a physical keylogger assuming you use an external keyboard like one time.
That's not really the same situation, if someone's trying to bug you they don't want to be caught, if they were willing to do illegal violence they'd probably do it first, or if they're a government, you have way bigger problems.
