wind effect on high poly mesh,adding wind to 3d object

Hi !

What would you recommend to animate, or get a kinda wind effect on a HP mesh ?

I need to get some scanned roots moving as if they were underwater, slowly rippling or undulating. I think i need to use a shader but im already using an arnold hdrp shader, meaning ill have to edit that in the shadergraph ?

The final goal is just a video, no need for any interaction whatsoever.

Thanks a lot for your inputs !!!
