Disable callback for some functions

[Dranaxel]

Hi,

First of all thanks for the package, I've been able to create many CLI for my team with so much ease, byebye argparse 👋

My question is: is there a way to deactivate callback for a se of function ? I have a set of command needing arguments but one of them don't.
