But just to be clear, telegram is not a privacy nor security app. It's just a communication app. It's fine that you use it, but just making sure you aren't calling an orange an apple (eat whatever fruit you want, I'm not a cop).

Sure it's possible. Signal does do this as well as many VPNs, things like encrypted DNS, tailscale and so on.
It's important to remember that it's also not binary. There's a whole range of metadata is. You can leave a footprint that's a very clear image of your shoe or you can leave a footprint that's a smudge that's only approximately in the size of your shoe. If you're concerned then the difference matters a lot.
While you won't leave zero trace the aforementioned apps (like signal and mullvad) do minimize the collection to the point where it isn't very useful. I mean it's metadata that you're a person, but that's not going to be helpful to identify you. Even knowing your gender probably won't but metadata's power is in it's accumulation.
