If you are meaning run at x16 for your GPU then so long as you are using the top
PCIe x16 slot you will be running in x16 mode. Windows will lower the bandwidth
when power saving so if you check (using something like GPUz) when they GPU is
idle it will show x8 or even x1 depending on drivers/settings. Simply apply a load
to the GPU and the link speed will increase to x16.

The reason there is no setting to force x16 is because it's all handled by drivers
these days and a forced setting can cause instability/conflicts.
