I also tried to change /etc/network/interfaces, but there is not many examples available about this.
I finally solve the problem by adding files to /etc/systemd/network as explain here :
So I add "br0.netdev"
MACAddress=0c:c4:7a:e6:ad:dc <====== the bridge MAC address that match the LAN network card
Than added "br0.network"
Then Modify "Openmediavault-eno1.network" like this :
Name=br0 <======= Change in file is here. Link to the bridge
