The jetson orin nx is connected to a virtual display and the GPU is not available

I use nomachine to remotely control the jetson orin nx and use a virtual display to connect to the nx. When using a single nx, the problem as shown in the figure below is that the GPU is always 0%, but when the nx is connected to the real display, the GPU will run normally. How do you solve this problem?
