Como usar o setpci para definir a velocidade do link?

Question

Eu tenho um 660TI conectado ao meu notebook via expresscard. Eu sei que o slot ExpressCard é capaz de velocidades PCIe-2.0;

Como você pode ver, a placa gráfica agora informa que só pode suportar PCIe 1.1 (2.5GT / s)

A minha pergunta é, como posso usar o setpci para definir a velocidade do link para PCIe 2.0 / (5GT / s)? Sistema operacional é o Windows 10 Pro
