Proxmox Private Vlan Feature

[zgasparian]

I'm migrating from VMWare-ESX to Proxmox. Previously I managed to used Private vlan on vmware and enhanced security for my customers and also used /32 IP address per customer.
now I am not able to find a solution for this case in Proxmox.
cloud anyone guide, what they have done to increase L2 security ibn their farms?

Thanks
