I have no VCCIO reading in HWINFO64 and I have no VCCIO reading in BIOS either. I've tried reaching out to gigabyte support about it and they suggested it was product segmentation. However, The Z490 Vision G has the same exact VRM and Bios chip size as the Z490 Aorus Ultra and that indeed has VCCIO voltage readout. Here's a picture of my voltage readouts.
Love HWINFO64. Keep up the great work.
