Cheat detection can't be disabled from the command line.
If you don't want victorypoints in the game, simply leave the switches out. (--requiredvp, --totalvp and --captialvp). Getting VP but no condition is possible, but I do not know how, exactly.
If this doesn't help, please try to give an example of what you are trying to achieve.
Also note that
the command line parser is broken, which sometimes makes it ignore certain options. If an option strangely doesn't work, try moving it to the beginnning of the command line.
