I couldn't find a solution for firmware upgrades crashs. But a workarround is good for me.
I got a bios file from a similar machine with Monterey, clean ME and edit serial number. Then i able to install OS 10.14+, on genuines SSD ou Nvme + Adapter, without issues.
Bios .bin is attached (don't forgot to change serial and validate F-sys to use this).
BootROM Firmware: 428.40.10.0.0.
