vCenter 6.5 VCSA HA Affinity rule settings not found

Hello, I have installed VCSA 6.5 GA release and I created VM-Host group, VM-Host rules, but after that I cannot find the "Edit vSphere HA Rule Settings" to enable "vSphere HA should respect VM to Host affinity rules during failover" host affinity rule settings. HA and DRS both are enabled and configured. I am running a two-node stretched VSAN cluster with a witness host.

see the screen below that what I am actually looking for:

but see below what I am seeing on my cluster configuration, there is no HA Rule Settings on 6.5 - I cannot find where it is

please let me know anyone from here, where to find this affinity settings.

Thanks
