Losted OCLP boot icon on Mac bios

Hello everyone, can I help something? I went on my MBP 2014 in a safe mode, left it, and when starting, the MacOS launch icon through OCLP disappeared. Now the laptop freezes to 30% of the system load. Is it possible to somehow restore EFI or at least save all the data that is stored on it for pure reinstallation?
