+**Note — Mapping a Single GPU**
+> If you need to map only a specific GPU into the container, remove both `--privileged` and `--device=/dev/dri` from the `docker run` command, and replace them with the following device and mount options (example for the first GPU):
+
+```bash
+--device /dev/dri/renderD128:/dev/dri/renderD128 \
+--mount type=bind,source="/dev/dri/by-path/pci-0000:18:00.0-card",target="/dev/dri/by-path/pci-0000:18:00.0-card" \
+--mount type=bind,source="/dev/dri/by-path/pci-0000:18:00.0-render",target="/dev/dri/by-path/pci-0000:18:00.0-render" \
+-v /dev/dri/card0:/dev/dri/card0 \
+```
+
+This way, only the first GPU will be mapped into the Docker container.
