Standard bridge and vSwitch on the same physical NIC?

Hey,

I am using Open vSwitch on my PVE nodes, and wanted to integrate Veeams new backup solution to PVE.
But in the current version of Veeam, they do not support Open vSwitch - https://helpcenter.veeam.com/docs/vbproxmoxve/userguide/system_requirements.html?ver=1

My nodes only have 1 NIC, so i tried to use the physical NIC for both the Open vSwitch and the standard bridge (not sure it would work, but had to try).

Code:
auto lo
iface lo inet loopback

auto enp3s0
iface enp3s0 inet manual
        ovs_type OVSPort
        ovs_bridge vmbr0

auto vlan10
iface vlan10 inet static
        address 192.168.10.21/24
        gateway 192.168.10.1
        ovs_type OVSIntPort
        ovs_bridge vmbr0
        ovs_options tag=10


auto vmbr0
iface vmbr0 inet manual
        ovs_type OVSBridge
        ovs_ports enp3s0 vlan10

auto vmbr1
iface vmbr1 inet manual
        bridge_ports enp3s0
        bridge_stp off
        bridge_fd 0

iface wlp4s0 inet manual

When applying i get this error message:
Code:
ifreload -a
warning: vmbr1: apply bridge ports settings: cmd '/bin/ip -force -batch - [link set dev enp3s0 master vmbr1]' failed: returned 1 (RTNETLINK answers: Operation not supported
Command failed -:1
)


Is my config incorrect, or is it more likely that i am trying something unsupported here?
