Network analyst- slope restrictions

I have a road network with attribute 'speed' and a DEM raster and I need to calculate the service area. I want to use the DEM raster to specify the speed in hilly areas. The idea is that the car goes uphill slower than down the hill. Is it possible to set a lower speed when going uphill and not to change the speed when going downhill? The speed depends on the steepness of the slope and slope values are divided into 4 categories. 


Is it possible to set it in Network analyst using ArcGIS Pro or is it only possible using Python?


Thank you,
