NGINX try_files across multiple drives on Windows

I am moving nginx out of a Linux VM to the Windows host for performance reasons and I'm having trouble with this part.

On Linux the configuration is:

root /;

try_files /mnt/m$uri /mnt/d$uri /mnt/l$uri =404;

Where /mnt/m, /mnt/d and /mnt/l are the mount points of the M:, D: and L: drives respectively.

On Windows I tried

root /;

try_files M:$uri D:$uri L:$uri =404;

but it throws this error

*1 GetFileAttributesEx() "C:L:/[...]" failed (123: The filename, directory name, or volume label syntax is incorrect)

It seems / is interpreted as the C: drive, it's the drive that nginx runs from. I also tried root ; and leaving the root directive out altogether but nothing worked.

I managed to do it by nesting(?) named locations. Though be careful as any headers/options you set in the main location block won't apply in the named locations, at least in my experience. @IvanShatsky's solution with NTFS mount points seems to be a lot better.

location /  {
    root "M:\\";
    try_files $uri $uri/ @ddrive;

}

location @ddrive {
    root "D:\\";
    try_files $uri $uri/ @ldrive;
}

location @ldrive {
    root "L:\\";
    try_files $uri $uri/ =404;
}
