ABS usually cannot be defeated, and doesn't make sense to. Some systems use the ABS system for front to rear proportioning as well, eliminating mechanical proportioning valves. Pulling the ABS fuse would be a bad idea.
Specialized / Enthusiast cars would be exceptions to this, they often have full defeat track modes.
All depends on the manufacturer. There are a few that don't want you to have any control. Some allow more.
