寻求帮助：docker-compose持续清除daemon.json内容，导致故障

I have a physical machine installed with the OMV system, not using a virtual machine. The system versions are as follows: OMV 6.9.9-1 (Shaitan), Linux 6.1.0-0.deb11.13-amd64, docker-ce 5:24.0.7-1debian.11bullseye, docker-compose-plugin 2.21.0-1debian.11bullseye.

Issue: My machine has an Nvidia GPU installed, and the drivers are installed correctly. Since my Docker setup requires GPU utilization, I modified /etc/docker/daemon.json as shown below to enable proper functionality:

root@omv:~# cat /etc/docker/daemon.json 
{ 
  "data-root": "/var/lib/docker", 
  "runtimes": { "nvidia": { "path": "nvidia-container-runtime", 
  "runtimeArgs": [] 
  }
 }, 
  "default-runtime": "nvidia" 
}

However, whenever I modify or create a new yml file in the Compose file menu and save it, the system automatically clears the content I added in the daemon.json file. Even changing the file permissions to read-only doesn't work. This prevents Docker from starting and functioning when GPU utilization is required:

root@omv:~# cat /etc/docker/daemon.json 
{ 
  "data-root": "/var/lib/docker" 
}

Hence, I'd like to know the reason behind this issue and what settings I need to apply to rectify it. Thank you!

谢谢gderf，谢谢版主chente，我把docker存储留空，问题似乎就解决了，自定义的daemon.json就不会再被compose修改了。
