Un-allowed DMA-capable bus/device(s) detected

I have a I/O LPC Controller - 0284 for Intel(R) 400 Series Chipset Family On-Package Platform Controller Hub. I read the instructions to whitelist this device because it is causing errors with Microsoft Intune compliance policies. It said to contact the hardware vendor to see if this device has external DMA ports before whitelisting it. How can I found out if this has external or only internal DMA ports?
