NeoCodeium is independent plugin, so it is nothing special how you should configure cmp. The only thing is definitely overlapping is the ghosttext it should be obviously disabled in cmp (it should be disabled by default).

I suggest making one of the plugin (neocodeium or cmp) to complete only on demand (with a kely). Personally, I have set manual completion in cmp, but it could be done vice versa:

cmp.setup({
  completion = {
    autocomplete = false,
  }
}

You can also set its events to disable neocodeium when cmp menu is visible. I have explained this setup here https://github.com/monkoose/neocodeium?tab=readme-ov-file#-tips
