1) Run the game first
2) Run the trainer as admin
3) DO NOT ACTIVATE WITH F1
4) Disable the internet driver or disconnect - it means UNPLUGGED.
5) Load the game - they will be in offline mode
6) Activate with F1 then use any options
7) You need to remind OFFLINE until you quit the game to desktop
That's not hard to do it.
The physical disk is obsolete and Uplay on PC can run without need any physical disk, so it don't going to make any difference, but console like PS4 and Xbox One need physical disk if you don't own digitally, so for PC, it is 100% digitally.

The game can be put in offline mode, can't disable EAC though without crashing said game for whatever reason (Even in offline mode which is weird.) so what that software does in the background could indeed a bit of a risk though seeing how there's bots and what not for For Honor it doesn't seem to be all that perfect even if it's very strict with restricting access to the software.
As PWizard already wrote in this thread:
'Anything that their server detects as unusual or "impossible" based on your play time will likely flag your account and trigger a ban.'
The only way to find out is to try it for yourself.
Ok thank you.
I think Ubi Soft can answer your question better as of what is logged and what is passed on to their servers.
