Should be possible through EGR temperature hysteresis method.
After EGR map there are two 8x1 maps like this
0008 2331 2531 2731 2831 2881 2931 3031 3131 0064 0064 0070 0096 0128 0128 0128 0128
The columns represent temperatures, 0.1 factor, -273.1 offset (temp range -40 to +40).
Set the values to 0 for both maps, this should keep EGR closed for all temperatures, while airflow should be adjusted automatically.
