I guess there is P24S08 or L08 EEPROM on thinkpad L440 motherboard. If you can find out this EEPROM, you can unlocked yours.
Watching this link (https://www.youtube.com/watch?v=ANZjUPUYE7s).
P/S: I used to unlock Thinkpad L540 (not thinkpad L440) via this menthod. I attached "L08 EEPROM location" on Thinkpad L540.
Good luck to you.
