I need help with my Voxel Game


I am a 4th year ESO student and I have hardly used the Unreal Engine, it is programmed little but for the first time in 9 months I see it necessary to go to a forum for help.

My idea is to create a procedural world, and with Noise, I used Simplex Noise but it does not allow me to randomize or interact with each loose block, since they are instantiated meshes and when changing a change all, I would like to ask for help or a tool, thanks
