2008 Acura TL'S Timing Belt Tensioner Noise?

Hi guys, I have a 2008 acura tl type s had the complete timing belt service done around 130k miles and now its around 146k. When I start the car cold its making this rattling noise and when it warms up it goes away so I tried to look it up online for whats maybe causing it and I’m seeing a lot about the timing belt tensioner and its kinda it for me base on the noise its making and the other people describes having the same issues. So my question, is it possible that if its really the tensioner is the problem can you just replace that part only?
