Hi, generally the Maya plugin is very old, and its development has been halted. We are not able to provide any kind of tech support specifically for the Maya plugin, until official development is started (which will happen at some point in the near future).
In the 3ds Max version, you can find "lock sampling pattern" option in the Performance tab. Unchecking it will make the noise pattern random across all rendered frames. This is sometimes needed when using denoising in post production, to get rid of visible static splotches.
