@A5trocat As a workaround, you could try disabling Secure Boot, in which case the variables won't even come to play and therefore your system should boot if that was the only problem. Secure Boot is an optional security enhancement, not a requirement. In terms of getting Secure Boot capability back, I'm surprised the reset methods you tried didn't work, but just out of curiosity, did you try the "Reset to Factory Defaults" option within the BIOS Setup interface itself? I think the battery is just a real-time clock battery, in which case removing it might not actually reset your BIOS settings. And I'm not sure about that jumper you mentioned. Other than that, maybe try running a BIOS update, even if you'd be reflashing the version you're already running?
