Yes, but no! So, GRC Variables are really a GRC concept, and you'd need to break multiple layers of encapsulation from within a Python block just to alter them. Really, that's possible with a simple callback function, but please don't.
Instead, the appropriate way of dealing with this would be giving the signal source a message port, on which it accepts new values via message. Then, from your Python or C++ block, just send a message.
