sorry for taking a tangent and let me preface by saying I’m not criticizing your setup or desire for security at all. it’s obviously adding a particular kind of physical roadblock to what stealing your stuff would require.
but I discovered that BIOS setting at a young age and have had this burning question about what exactly does it protect? it does prevent booting but in a situation where somebody has access to your computer that only really stops them from using your motherboard right? is OP’s usecase the actual intention, where somebody would be required to physically steal at least part of the computer in order to access it?

Are CMOS batteries still a thing? Removing that and the laptop battery should wipe the BIOS to the default settings

That hasn’t worked on any (good) machine for the last 20 years. Especially now in the EFI age any important settings like that are stored in nvram.

Maybe you can check the manual if the laptop has a CMOS battery. If it does, you’ll have to take apart the laptop to remove the battery for a few minutes, which will reset all the settings.
