Redirecting attention seeking behavior?

Hi all! I started my full takeover in a high school classroom in January and I have one particular student I'm struggling with and I need some advice. This student isn't a bad student by any means, but she tends to be disruptive in noisy ways, whether or not I'm speaking.

For a while, I handled it by redirecting her every time, but now I was told that her behavior is attention seeking and so I shouldn't reinforce it with any attention, including those redirections. So I started to ignore it/just saying I'll wait/trying to avoid giving that attention. That isn't working at all and the behavior is continuing, and now it's borderline impossible for me to be heard when I'm giving directions.

I'm sure the right solution here is painfully obvious and I'm just missing it because it's stressing me out, but how can I stop the behavior without reinforcing the attention seeking?
