In a way, yes. You can call `wg addconf` from a wg-quick PostUp hook to include
another configuration file containing only peers. However, the recommended way
of doing this if you are using a configuration management system
(puppet/ansible/salt/etc.) is to use a template that will concatenate the
interface configuration and peer definitions into one file.

Note that WireGuard will ignore a peer whose public key matches the interface's
private key. So you can distribute a single list of peers everywhere. Only the
[Interface] section needs to be customized per machine.

Hope that helps,
