      I've found something interesting.
      @JoergS5 gave me a hint.

      My DueX2 is a version 0.8 and when I read the features section from the DueX2 and DueX5 I see this:

      Duex 2 v0.8 and older

      2 additional TMC2660 stepper motor drivers with stall notification. 2 additional extruder heater outputs. 2 servo outputs with 5V power and 5V signal levels, sharing control channels with the heaters. So you can use unused heater channels to drive servos. 2 additional endstop inputs with indicator LEDs and 3.3V/5V voltage selection. These are also usable as outputs. 6 additional PWM controlled fan outputs*, also usable for driving LEDs etc. The output voltage may be switched between 5V, 12V and VIN . 4 uncommitted general purpose I/O pins. 12V switching regulator, for generating a 12V supply for fans, LEDs etc. when the VIN power is higher than 12V. 2 additional thermistor inputs. Support for 2 more thermocouple or PT100 daughter boards, supporting up to 4 more sensors. Optional 5V external power input for powering servos, fans etc.

      Duex 2 v0.8a and newer

      2 additional TMC2660 stepper motor drivers with stall notification. 5 additional extruder heater outputs. 5 servo outputs with 5V power and 5V signal levels, sharing control channels with the heaters. So you can use unused heater channels to drive servos. 5 additional endstop inputs with indicator LEDs and 3.3V/5V voltage selection. These are also usable as outputs. 6 additional PWM controlled fan outputs, also usable for driving LEDs etc. The output voltage may be switched between 5V, 12V and VIN . 4 uncommitted general purpose I/O pins. 12V switching regulator, for generating a 12V supply for fans, LEDs etc. when the VIN power is higher than 12V. 5 additional thermistor inputs.

      Now the crazy part. I have a 0.8 and not a 0.8a but I can use the servo ports 1-3. This is really strange and does not apply to any logic.

      May you could tell me where I'm wrong or misunderstand something?

      Yes, that should work, including adding the M307 command to config.g. Make sure there isn't another M307 H2 command in config-override.g.
