@Redheadrambo You could add a temperature daughterboard, which would give two additional temperature inputs (or four if you added two temperature daughterboards), see https://docs.duet3d.com/Duet3D_hardware/Accessories/PT100_Temperature_Daughterboard or https://docs.duet3d.com/Duet3D_hardware/Accessories/Thermocouple_Daughterboard
However, these are only available with connections for thermocouples or PT100 sensors, not thermistors or PT1000.
