Openvpn – How to automatically add a local route after OpenVPN start

I have a container which routes all its traffic via OpenVPN. This is done by OpenVPN via a combo of

0.0.0.0/1 via 10.8.8.17 dev tun0 
128.0.0.0/1 via 10.8.8.17 dev tun0 

which masks the default route (which is still there when OpenVPN shuts down)

I need to explicitly add a route for a local network which would direct packets via eth0 and not tun0.

This is manually done via

ip route add 10.10.10.0/24 via 10.10.11.254 dev eth0

after OpenVPN has started.

How can I do that automatically upon OpenVPN start?

I tried to add

route 10.10.10.0 255.255.255.0

to mu .ovpn config file, but this leads to a new route via tun0 (which is quite understandable as there was no specific information about the NIC to route through – but I did not see anything available in the doc either)

# ip route
(...)
10.10.10.0/24 via 10.8.8.17 dev tun0 

Is what I want to achieve doable though OpenVPN configuration or do I need to do it somehow outside the OpenVPN startup process?
