Hi,
first, i am french so excuse me if my english is not good.
-I am in hell dudes, help me please, i am ready to pay for this help. I really need a modded bios to disable HPET on Z390 pro carbon gaming.
-The motherboard is fking hell, trust me, there is NO fking driver for xhci usb 3.0/3.1
the only driver can be install is a fake and have no *.inf files, or bad *.inf files. so i just enable hand hci profile on bios to get regularity for my mouse. If you know something other, i am ready to learn.
Thanks a lot 
Your humble servitor.
