Hi Leandro
Find below a network configuration, assuming that PVE resides on the
native/untagged VLAN like the other VMs you did not list.
As you did not mention the IP address of the PVE host I assumed 192.168.0.1/24.
You can either enter this in /etc/network/interfaces directly or configure it
in the PVE GUI.
vmbr0 already exists, I guess, for the untagged Vlan. and is connected to en1
which used to be an untagged interface but now is a trunk, carrying the
untagged traffic in addition to the tagged traffic from vlans 10 and 20.
You just need to a vmbridge for each of them, linking it to the vlan
sub-interface of trunk en1.
1.Create: Linux Bridge
Name: vmbr10
Bridge ports: en1.10
Comment: access ports for VLAN 10
2.Create: Linux Bridge
Name: vmbr20
Bridge ports: en1.20
Comment: access ports for VLAN 10
That's where you hook up your VMs to.
Starting with PVE 6.1 you can apply changes without rebooting the host.
https://pve.proxmox.com/wiki/Network_Configuration#_apply_network_changes
The working VMs without VLAN tags should continue to work.
I would recommend though, to reboot the host after fundamental network changes
like this.
Note that I could not test the proposed config but I am running a very similar
one and it has been working for years (since 5.x).
