How to remove route on openvpn connection?

Question

openvpn

Greetings.
Such a thing, I connect via openvpn to organize access to the local network.
Despite the fact that on the server, as it were, there is a ban on the Internet through VPN, it doesn’t matter why, sometimes, the Internet tries to break through the VPN network.
I wanted to know if there is a command for the client configuration to delete the route created by the client...?
In Windows, I write in the console route delete 0.0.0.0 mask 0.0.0.0 192.168.100.1 and everything falls into place, I would like it to be automatically either deleted or not created

OpenVPN allows you to execute scripts on connection and disconnection, the config parameters are up and down, respectively.
