DELL Precision 7540 Bios password

[Lubazi]

SERVICE TAG: 270Q3Z2
MAINBOARD: EDA50 LA-H271P Rev: 1.0

Hello, my BIOS has a password, I need a BIOS that unlocks my password.
I only have WINBOND 25Q80DVSIG1939 on the board
Found as a BIOS chip, a 1 MB file is stored there. I uploaded this file here. If I'm wrong and another chip is the BIOS chip, please let me know.
I am grateful for any help.

Thank you very much, it was on the back, now I have uploaded my locked bios. can you unlock it?

Let it run for 2 mins, it will restart several times with no image. 1st boot Press F2, write service tag, save (apply changes), reboot, press Alt+F to exit factory mode.
