Exhaust Manifold Heat Shield Rattle fix?

I have a 2015 Base CT200H. My heat shield is rattling against the exhaust manifold. I took it to an exhaust shop and they explained 1 out of 2 mounting tabs where the shield would bolt to has broken off completely. They said it was impossible to do any sort of tac welding because they couldn't reach the manifold without a large number of labor hours to reach it. IE: engine components or whatever would have to come off for them to gain access.

They suggested I look on the internet to see if there's another fix that's possible, but they couldn't come up with an idea to reduce or fix the rattle.

Obviously, I can't just pull the heat shield off because it's still attached to the manifold with one bolt.

Does anyone have any experience with this or a suggestion on how to fix this? I just want the rattle to go away.
