I have a Dell Optiplex 3090 MFF i5-10500T (chipset Q470) with AMT state 3 disabled.
I want to turn AMT on but I cannot dump my bios because there is no service jumper like in many other older dell PC's.

Motherboard in service manual with jumpers

My motherboard is different. It is Foxconn IPCML-RN/ZB without any jumpers:

In older models service manual has a notice that:

Zitat

---

The legacy jumper enabled RTC reset has been retired on these models

---

Nowadays there is no RTC reset jumper, no reset password jumper and no service mode jumper.

Is there any way to turn the service mode on? Maybe I should short 2 unsoldered pins near CPU FAN socket, but I do not have motherboard scheme.

Thank you in advance for any suggestions.
