Set ACL WSL launch settings for automount

Question

I am trying to set acl mount option on /mnt/c drive.

Tried to follow https://docs.microsoft.com/en-us/windows/wsl/wsl-config#set-wsl-launch-settings by setting mountFsTab = true on /etc/wsl.conf

then LABEL=cloudimg-rootfs / ext4 defaults,acl 0 0 on /etc/fstab.

It doesn't seem to work.

…/Documents/Projets:$ pwd 
/mnt/c/Users/Warth/Documents/Projets

…/Documents/Projets:$ sudo setfacl  -m u:kwaadpepper:rwx blog
setfacl: blog: Opération non supportée

(Operation not supported) any hint ?
