I want to have a mod that disables hacking for all factions, except for the umbral choir. You can still defend yourself, but you never get access to a "ongoing hack".
Is that possible to mod in?

A modder will have to be hired for a donation. In the first ES it was possible to do this, there was a faction disharmony not using dust. If they did not implement it in this game, then there are difficulties with the realization of the idea.
The game will become extremely asymmetrical, then it is necessary to increase the hacker defense skills of the other factions.

What if you use custom factions?

The ESG 1.6 mod has an option to disable the PVP hacking, so players can't do things that affect other players.
