If you don't mind physically opening the laptop, you open it and take out the CMOS battery, boot it up without it then shut it down and put the CMOS battery back in and boot. The BIOS password will no longer bet set. I don't know if this still works but it used to on older laptops.

Modern UEFI uses Flash Storage and CMOS is only relevant for the computer time keeping (though some UEFIs have a full CMOS to emulate BIOS behaviour)

Doesn't work anymore. The data is no longer stored in CMOS.

Sometimes it is the same chip but not the same range, so it's not cleared ever.
