Voxel quixel texture variation / remove tiling problem

hi all I’m trying to use the texture variation node to create some texture variation or break the tiling of the textures on my map, I’m using voxel to build my terrains and using quixel megascans , but i have to use something called ms_voxelquixel for my megascan texture parent, this is confusing becuase i have no idea where to insert my Texture Variation node cuz the way ms_voxelquixel is set up is very complicated, heres the code,

help is greatly appreciated appreciated , thanks
