[ceph-users] Ceph orch placement anti affinity

Let’s say I have 2 cephfs, and three hosts I want to use as MDS hosts. I use ceph orch apply mds to spin up the MDS daemons. Is there a way to ensure that I don’t get two active MDS running on the same host? I mean when using the ceph orch apply mds command, I can specify —placement, but it only seems like I can define the hosts, but not let’s say a primary host or something similar. Anyone with knowledge of how to do this or is it simply not possible?
