The BIOS password isn’t a security feature, it is a convenience feature.

At the very least you can just remove the drive and put it into another device. But also you can almost universally just remove the BIOS storage (or even just the battery) and replace it.

Maybe secure boot will change this if the BOIS is measured into the TPM on boot and use as part of the disk encryption key, but I don’t know if even Windows does that.
