Proxmox VLAN configuration can be challenging if you haven't seen how this is done. However, we walk through this process step-by-step and show how to make Proxmox VLAN aware, move the management IP, and add VLANs to Proxmox virtual machines.

You can find the code examples and written walkthrough here: https://www.virtualizationhowto.com/2023/12/proxmox-vlan-configuration-management-ip-bridge-and-virtual-machines/
