Hi Amos, 

For GPU and I/O settings, it should be part of the Intel TCC Mode setting in BIOS. 

GT-CLOS and WRC will be configured by enabling Intel TCC Mode in BIOS. 

You can refer to the real-time tuning guide https://cdrdv2.intel.com/v1/dl/getContent/640980 section 7.1.4 

The TCC Mode setting will minimize the GPU usage and allocate I/O into the cache.

Have you tried with the Intel TCC Mode enabled? 

What cache are you using? is it only L2 or L3 or a combination of both?
