GPU usage monitor for FreeBSD?

I am using FreeBSD on a personal desktop computer, and a nvidia GTX 1650 GPU. In my gnome system monitor (similar to task manager of MS Windows), I am able to monitor all the resources, including all the processor cores, RAM, swap memory, and other stuff. But GPU is not visible there. Is there any tool for FreeBSD to see the GPU activity/usage? GUI based is preferred, but CLI is ok as well. I did a lot of research, but could not find anything to monitor GPU usages. I do not want to over-clock the GPU. I want to only monitor it.
