@iamrkp are you a Service Provider? Under the SPLA usage rights, my company hosts unlimited Virtual Machines with ESXi that are licensed as Datacenter Core packs. We are audited every 3 years and just completed an audit. So, I am confident in this answer.
However, licensing desktops (Win10 or 11) is not covered in a mixed environment. Those hosts must be licensed separately and the cluster/host resources must be dedicated to desktops. You cannot have servers on those hosts. I don't recall if this was a Microsoft EULA issue or VMware EULA issue.
