The whole network stack of BlueOnyx doesn't use DHCP at all. When you 
install BlueOnyx DHCP gets turned off and static network settings are 
configured. And they remain static unless someone manually fiddles with 
it or maybe some third party software fiddles with it.

I can't imagine a way how the network settings would switch to DHCP on 
their own. So I'm as confused as you are why this has happened in your case.

The only way how you can still use DHCP on a BlueOnyx (there are some 
valid usage cased for this after all) is when you create the (empty) 
file /etc/is_aws. When that is present, all network related handlers and 
constructors will no longer have permissions to change your network 
settings at all. But even then: That doesn't switch your server to DHCP 
on its own and one has to manually modify the network config files to do so.
