P40显卡切片以RTX3090身份运行在虚拟机但无法在Windows11里实现”纵向“的显示方向

[tranvyhor]

您好，
我的P40显卡配搭550.127.06驱动在PVE 9.2.2宿主机上运行。
我对这块显卡进行切片，以RTX3090的仿真身份运行在一台Windows11(10.0.26200.8655)虚拟机上。虚拟机的显示器为两个VGX虚拟显示器（Display1和Display2）。

虚拟机的信息如下：

我的问题是，调用NvAPI_DISP_SetDisplayConfig函数进行设置，参数传入NV_ROTATE_90/180/270总是返回NVAPI_ERROR，无论是Display1还是Display2都一样：

我同时也发现Windows11显示方向无法修改为“纵向”：

是我的显卡驱动的问题，还是硬件问题？非常感谢
