Tikz "none at all" style

I'm creating a customisable TikZ pic where I want to enable or disable certain parts of it (e.g. some labels). Is there a style that I can pass to a node, pic, path or so that doesn't visibly draw it? So basically like draw=none, except that it should also extend to text, fill and so on.

One first try would be \tikzset{none/.style={draw=none,fill=none,text opacity=0}}, but I can't believe there is no "proper solution" for this. Maybe there is, and I just don't know which style to look for.

See for example how my first try could be used:

\documentclass{article}

\usepackage{tikz}

\begin{document}
    \begin{tikzpicture}[bla/.pic={\node {A};},none/.style={draw=none,fill=none,text opacity=0}]
        \pic at (0,0) {bla};
        \pic[none] at (2,0) {bla};

        \node at (0,2) {B};
        \node[none] at (2,2) {B};

        \draw (0,4) -- node[right] {C} (0,5);
        \draw[none] (0,4) -- node[right] {C} (0,5);
    \end{tikzpicture}

\end{document}

Edit: As Percusse points out, it might be hard to make TeX actually not draw it, so maybe it's easier to ask how to invisibly draw it.
