I'm not using anymore AGCM4 + RAMPS_144 but it seems that on AUX1 you have:

  VCC GND D1 D0
  VCC GND A3 A4

but VCC may be 5V/3V depending on J4 jumper (this goes also to IO pin)

AUX3 is (please note that SPI pins on AGCM4 are not like DUE but standard D50-52 may be redirected via solering pads):

 RESET GND SCK MISO VCC
  NC    5V D53 MOSI D49

AUX4 is:
VCC and not 5V

LCD144-A_Rev.A.pdf

As reference I add schematic

N.B. Ramps144 has been discontinued, because of developper health issues, then AGCM4 has de facto no shields available
