ceph-deploy doesn't support that. You can use ceph-disk or ceph-volume directly (with basically the same syntax as ceph-deploy), but you can only explicitly re-use an OSD id if you set it to destroyed before.
I.e., the proper way to replace an OSD while avoiding unnecessary data movement is: ceph osd destroy osd.XX ceph-volume lvm prepare ... --osd-id 10 Also, check out "ceph osd purge" to remove OSDs with one simple step.
