Are you referring to the camera view when you say Canvas? If this is the case, then this is not possibe - the camera view is always rendered.
If you're refererring to something different, please provide further details on what you mean with canvas.
Thx and greetings

Good day i am a new developer and i was wondering if anyone knew how to hide a canvas in unity so that it will only appear when the image target is shown
