Script to edit DNSCrypt-Proxy on-boot?

[ghost]

UDM now has "DNS Shield", which is simply DNSCrypt-Proxy, but it uses some insecure parameters in its DNSCrypt-Proxy.toml configuration file. I can know how I want to edit the file, but I don't know how to force my settings on boot. I don't even know how to force my settings after boot. Changing DNSCrypt-Proxy.toml settings in /etc/dnscrypt-proxy and executing "service dnscrypt-proxy restart" doesn't force my settings. The active file in the that gets over-written by udapi-server. I'd much appreciate knowing how to enforce my own DNSCrypt-Proxy.toml configuration on boot.
