You may need to compile some extensions if they don’t already have a linux binary. I had to do this with the f0plugins from fredrik olofsson (these are ugens). (assuming of course there’s source code for them)
Once compiled on norns, they should be installed at /home/we/.local/share/SuperCollider/Extensions on norns.
After that you’d need to create an engine or some other SC glue/code to access them from the Lua layer. I’m slowly working on this for some of the f0plugins.
