Secure boot is enabled. I can't access the boot menu so I can't change it.
Also, I cannot flash the BIOS from FreeDOS.(FreeDOS cannot be booted with UEFI.)(Use afudos)
And, In the case of afuwin, it fails due to an ffs checksum error.(In the case of afuwin, it fails due to ffs checksum error. (Include in the case of a dump(backup?) where nothing has been changed)...

Hello,
please help me unlock bios on this laptop
Modell:Epson Endeavor NA520E
BIOS:AMI BIOS/UEFI
BIOS Serial Number: 952006306
Motherboard:Epson 13M1
Secure boot:Enable

The key for the backdoor password is not displayed.
cmospwd failed because after running "ioperm.exe -i" I got the error "StartService function call failed".
I will not be able to access the boot options .
dual boot(Windows and Linux) is what BIOS password removal is for.
Booting from a USB flash drive will always boot into Windows, even...
