AlphaGo/MuZero are completely NN based and were so far ahead of the competition when they were developed they led to the whole wave of NN-for-eval that we seen now. And AlphaGo/MuZero doesn't compete in TCEC.
The chess community (especially the stockfish programming group) is very focused on improving their own system. I don't think the fact that is a the strongest system really means much - it's pretty clear they are leaving performance on the table. For example it wasn't until last year (!) that they moved to a GPU based training system.
