Hiding VM info from DxDiag

Hi all, Apologies if this question has already been asked a thousand times already but I seem to be going round in circles. I followed the Jim Browning video on making your VM stealthy and it mostly worked for me apart from a couple of settings as shown in the attached image.

Can anyone tell me how to hide this information without having to use tools such as up MSInfo32, upDXDiag etc.
