The configuration files for Hamachi on Linux are located in /var/lib/logmein-hamachi/. The base engine configuration resides in the file h2-engine.cfg within this folder. In a file named h2-engine-override.cfg you should be able to override some values from the h2-engine.cfg file.
You can create the override file yourself if absent. But since you mention using Haguichi this file should be present already (Haguichi creates this override file with Ipc.User line when you hit "Configure" the first time, so that you can control Hamachi using your normal user account).
Because everything in /var is owned by root, you will need to use sudo to edit the override file:
sudo nano /var/lib/logmein-hamachi/h2-engine-override.cfg
After you are done editing the override file you need to restart the Hamachi service in order to have your changes applied:
sudo systemctl restart logmein-hamachi
I hope this information will get you a bit further. Good luck and please share anything you find out!
