Officially the ME is updated along bios versions released by the OEM, period.
If u want to update it manually, follow the guidelines here: Intel (Converged Security) Management Engine: Drivers, Firmware and Tools
Do NOT skip the reading to avoid mistakes and further useless posts with questions regarding information, that is provided in the guidance and simply users skip it…
All the reading is necessary to understand it and in ur case the ME 12 notes are not to skip at all.
Backups is a MUST, common fails errors can occur during operations as they are often due to security implementations by OEMs in the SPI/Firmware.
