It's a strange request -- I think most programs will try to deal with an empty argument differently than it would without that argument at all.
In this particular case, ["cargo", "clean", "--"] would work to pad it to 3 arguments, but you couldn't go any further that way.

argv passed to execve is a pointer to an array of pointers . So just set the pointer in the slot after the last argument to null instead of pointing to an empty string. Then any further elements will be ignored.
