Command without completion?

Hi,

is possible to create a command without completion? I want to rewrite a lot of scripts to this method, so we can implement all into Radial menu, but this way, I would like to avoid file of suggestions for command whenever someone will write / even though they should have no need for that.

Yes, I will do certain restrictions and job checks, I just don’t want to have million suggestions in the chat, that’s all.
