If you use macvlan mode you do not have to change the network config in the host (you create a macvlan profile, assign it to the containers and config the network inside container). I have read that macvlan is faster than bridge but the host can’t communicate with his containers. Look at Macvlan vs network bridge
In Another ‘networking issue’ or ‘how to connect containers to more than one network using a bridge or macvlan’ you can see an interfaces file that I have used in several Ubuntu 16.04 hosts without problems (previously I installed the bridge-utils and verify the interface’s name). I can not assure 100% that you have no problems; but you can ask the hosting company if they have any limitations regarding the use of containers and bridge mode (or macvlan).
