We already have a ceph cluster so we would like to reuse that instead of hyperconverging. Is there any way do do this with charms or do we need to look into openstack ansible? This is not a typical deployment but is something that is possible - you can use the ceph-proxy to wire your existing ceph deployment into charm deployed OpenStack: https://jaas.ai/ceph-proxy Basically it acts as an intermediary between the OpenStack Charms and the existing Ceph deployment.
