I am right here here. From the article you posted:
A lo que luego agregó, "¿Qué puede hacer Brasil?. Vamos a suponer que haya una invasión militar a Venezuela, allí la decisión va a ser mía pero primero voy a escuchar al Consejo de Defensa Nacional y al Parlamento...La tesis de una acción armada es respaldada por Bolsonaro pero no por los militares que integran su gobierno, entre ellos el general y vicepresidente Hamilton Mourao."
He is playing to his base. Nor the military or Congress (or the general public) wants anything to do with Venezuela and they are all very vocal about it.
Brazil will not invade Venezuela. Even if it wanted, it has no means to do so. The Brazilian military is a defensive force, not an expeditionary one. It has no means, resources, training or doctrine to conduct large scale invasions. Caracas might as well be in China, as far as the Brazilian military capabilities to project power beyond its borders are concerned.
