Hello,
I have a small inconvenience, while using pvpython with my script when i use the line:
`animationScene1.AnimationTime = timeSteps[-1]`
even if i dont have anything displayed, the terminal will open a x11 window, how can I stop this window from being created (or if I should not be using `animationScene1.AnimationTime = timeSteps[-1]` and instead maybe something else? how could I go to a specific timeStep of my simulation without using this line?)
bonus question about another small inconvenience when running my pvpython, i am getting on the begining the following message:
> VisRTX 0.1.6, using devices:
> 0: NVIDIA T600 Laptop GPU (Total: 3.9 GB, Available: 2.6 GB)
is there any way to stop this from being printed? (outside of sending all output to a dummy file?) I have some printing things on the script that would love to keep being printed but would like to remove this lines so it gets less convoluted.

I agree this should not be printed, please open an issue.

i will use pvbatch, dummy from my side, but could you confirm me if i am missing something or we SHOULD use:
animationScene1.AnimationTime = timeSteps[-1]
and there is no other way to ‘change the current time’ when using paraview(in scripting)? I am asking due to this problem I [faced](https://discourse.paraview.org/t/filters-not-being-updated-when-using-pvpython/17347/2)

changing the animation time triggers a render, which opens a window.

yes yes, what I mean is if I should be using something else instead, that changes the timestep which I am 'currently working’ without the rendering.

pvpyhon takes an argument to prevent windows for popping up. `--force-offscreen-rendering`
