VPN

According to numerous maunals, I raised my VPN.
With the rise of the VPN, I finished and at this stage all the manuals in Google end.
How to disable all logs on a machine?
It costs VMmanager on the main one and VDS is allocated for these cases. I would like to completely cut off any logging both at the level of the main machine and at the VDS level.
I read that in any case the logs are maintained by the DC. But I also have physical access to the server, only the provider is higher.
