Help, I corrupted the EFI on my MacOS!

I wanted to replace the SMBIOS, but it gave me an error and now I can't start the system to change it. I don't have data backup and the only thing I have left is to use a PC with Windows and an enclosure for the SSD. Any solution to recover the boot? I have a “MacBook9,2” 2012 I7 with MacOS Sequoia and OpenCore Legacy Patcher 2.4.1.
