Command "set COMMANDLINE_ARGS="--device-id=1" does not work

Nobody has claimed this yet.

I have gpu 0 rtx 4090, the rest are 3090.

_Launching Web UI with arguments: --device-id=1
Total VRAM 24564 MB, total RAM 130950 MB
pytorch version: 2.1.2+cu121
Set vram state to: NORMAL_VRAM
Device: cuda:0 NVIDIA GeForce RTX 4090 : native_

Despite the command, it still uses my GPU 0 - 4090.
I want to run stable diffusion forge on my second GPU. How to achieve this?
Automatic1111 I used previously did so.

I use **\stable-diffusion-webui-forge run.bat** windows batch file to run it.
I edit **\stable-diffusion-webui-forge\webui webui-user.bat** to set which GPU to use.

```
@echo off

set PYTHON=
set GIT=
set VENV_DIR=
set COMMANDLINE_ARGS="--device-id=1"

@REM Uncomment following code to reference an existing A1111 checkout.
@REM set A1111_HOME=Your A1111 checkout dir
@REM
@REM set VENV_DIR=%A1111_HOME%/venv
@REM set COMMANDLINE_ARGS=%COMMANDLINE_ARGS% ^
@REM --ckpt-dir %A1111_HOME%/models/Stable-diffusion ^
@REM --hypernetwork-dir %A1111_HOME%/models/hypernetworks ^
@REM --embeddings-dir %A1111_HOME%/embeddings ^
@REM --lora-dir %A1111_HOME%/models/Lora

call webui.bat
```

Start by tracing how webui-user.bat passes COMMANDLINE_ARGS to webui.bat, then inspect how the --device-id value is parsed during startup. Use the reported batch-file configuration and startup output as the reproduction case. Done means the launch selects the requested second GPU rather than cuda:0.
