Voronoi node pattern looks differ between devices

I use the Voronoi node in shader graph to create a various surfaces like ground, rocks, etc.

I first created a seamless voronoi texture shader using the Position node:

This allows me to place any map objects with the same material together so that they can form a single seamless surface (with a voronoi pattern on it). But this causes an unexpected rendering issue. When I tested my game on multiple devices, I saw that the Voronoi noise had a different pattern:

Unfortunately pseudo-random Voronoi node hasn't any random-seed parameter so that I could be deal with this. I have already spent several days trying to solve this problem and now I am here. Any help is appreciated.
