Not a bad idea, but I've never seen any such chewy. So of course I do a quick web search and they do indeed make such a toy. https://www.amazon.com/Remote-Control-Treats-Inside-Hours/dp/B08WWNR1ZX But the reviews don't look like it holds up to chewing very well.
However, I would worry that the dog recognizes the shape as something it's OK to chew, and makes the real remote more of a target. Might be smarter in the long run to make sure the remote is out of their reach. 😄
