There is a build for greatlte mentioned here [UNOFFICIAL BUILD] Samsung Galaxy Note 8 (2017) (greatlte) v1-t.
There is a thread from @Stricted on XDA https://forum.xda-developers.com/t/rom-unofficial-greatlte-sm-n950f-10-lineageos-17-1.4041979/
and sources can be found

Might be better if I had responded on a more relevant thread rather than this thread with the USA (see also Post #3) SM-N950U in the title.
