If you open an NC file in Indie the session will be downgraded to an Apprentice session and can no longer save in Indie (LC) format until you restart Houdini.

Sidefx explicitly offers a one-time conversion of NC/LC files to full commercial when purchasing a license (files have to be sent to Sidefx), but a quick google doesn't turn up an equivalent for NC to LC.

You should email sidefx support for a definitive answer.

Perhaps this is what you are looking for?

by default it doesn't appear in the tab menu in materialx builder only in karma material builder but it does seem to work in a materialx network with xpu if you paste it in.

I don’t know enough to give you a really good answer but since no-one else has answered in months I will chime in.

Vex will not work at all with Karma XPU/MaterialX.

I am not clear on why you don’t use the built in houdinioceanprocedural, but if you want to roll your own you might try diving into it down through the nodes until you get to the mtlxstandardsurface that shades the ocean. There may be something there you can use.
