@yasin lachini,
If you deploy kubernetes cluster on baremetal, you don't need to configure anything. That is because /usr/libexec/kubernetes/kubelet-plugins/volume/exec/ is the kubelet default FlexVolume path and Rook assumes the default FlexVolume path if not set differently.

My env:
rook-ceph/operator.yml (use default FLEXVOLUME_DIR_PATH) :

...
        # Set the path where the Rook agent can find the flex volumes
        # - name: FLEXVOLUME_DIR_PATH
        #   value: "/usr/libexec/kubernetes/kubelet-plugins/volume/exec"
...

After deploy,on node:

# ls /usr/libexec/kubernetes/kubelet-plugins/volume/exec/
ceph.rook.io~rook  ceph.rook.io~rook-ceph-system  rook.io~rook  rook.io~rook-ceph-system
