Locked Thinkpad X250 BIOS with Supervisor password

[Marian97]

Hello!
I bought an Thinkpad X250 with Supervisor password on. I was able to access most of the settings in BIOS but not Virtualization. In my desperate attempts to somehow reset the Supervisor password, I have entered it 3 times, of course the wrong one and then I was locked out of Windows and BIOS with the error: 199 system security - security password retry count exceeded. The only thing I can do is to enter the correct password which of course I don't know.
 
So, my kind request, if someone could please help me modify my BIOS dump in order to at least reset the incorrect password count so I can at least use my laptop like before, even with the Supervisor password, that will be great.
If the Supervisor password can be removed, that will be perfect.
 
Here is the BIOS dump: https://www.dropbox.com/s/0qyqdnakn7fsvcs/bios1.zip?dl=0
 
Thank you!
