SenseNDR.exe consistently using 10-20% of CPU


We've deployed MDE to a subset of our workstation, and found that SenseNDR.exe consistently uses 10-20% of CPU even on idle machines. Does anyone know what role SenseNDR plays within MDE and why it needs all this CPU? We aren't gong to be able to deploy MDE across the rest of our enterprise with this big a CPU hit. 

I dug around for a while, and it seems that SenseNDR is involved in device discovery, though if it serves other functions I can't say. Is it possible to fully disable Device Discovery since we have no use for it?

We were able to reduce it somewhat by globally disabling device discovery.
