WinPE x64 + fdert.exe not cooperate - FDE

[AE_PL]

I got notebook without  Zbook G9, i need decrypt the from WinPE with tool  fdert.exe without take out SSD. 

 

Problem is that, i can’t boot x86 winpe only x64 from USB Stick at Zbook G9. At bios i can only disable secure boot but i can’t change to legacy mode. 

 

If i try to use fdert.exe tool at WinPE x64 it says not is not right version of system.  

 

Any solution?
