Hi shweta,
I appreciate your patience.
There are 2 parallax options, first is the built-in parallax from WPBakery plugin for rows and columns, which is located in the general tab https://prnt.sc/4-2K7WUEI17U and WoodMart parallax, which is located in the design options https://prnt.sc/zBczbrMeX9Dl
You can see demos here https://woodmart.xtemos.com/layout-parallax/?opt=layout_parallax
It is also important to note that WoodMart parallax is disabled on mobile to avoid stretching and performance issues.
You are using Parallax effect from WPBakery, then it works as it is, we have no influence on it and cannot turn it off, improve, or change its operation in any way.
In additional to background parallax is not some magic trick, and using it actually has its cost. In order for the parallax effect to occur, the image must be larger than the container in which it is located, because of that the zooming effect is inevitable. In order for the image to scroll faster, it must be higher, and when it becomes higher, it zooms even more.
For example, if you make 2.0, it means that the image will be twice as high as its original size https://prnt.sc/PyEvXkB3Dx36. So in order to use high values of parallax speed – you need to use a taller image with the correct aspect ratio which there will be enough margin of pixel density during the zooming.
