The above should set up the direct-lvm for devicemapper. You can then configure docker to use devicemapper by adding this
to /etc/docker/daemon.json
{
    "storage-driver": "devicemapper",
    "storage-opts": [
    "dm.thinpooldev=/dev/mapper/docker-thinpool",
    "dm.use_deferred_removal=true",
    "dm.use_deferred_deletion=true"
    ]
}

In case, you want to revert the above changes, follow the below cleanup instructions
#================================
#To cleanup:
#Remove logical volume:
$ sudo lvremove docker
Do you really want to remove active logical volume docker/thinpool? [y/n]: y
  Logical volume "thinpool" successfully removed

#Should show empty
$ sudo lvdisplay

$sudo vgremove docker
  Volume group "docker" successfully removed

#should show empty
$sudo vgdisplay

#Now remove docker graph driver directory
sudo rm -rf /var/lib/docker/devicemapper
