There is no need for \noexpand before \NC. Even \NR is protected. In 
MKIV there are some more sensitive ones like \FR but in LMTX these are 
defined as \noaligned which permits them being protected too (the 
engine's alignments scanners have some lookahead properties that cna 
otherwise interfere).

     \NC \infofont\meaningasis \NC \NC \NR
     \NC \infofont\meaningasis \NR \NC \NR
     \NC \infofont\meaningasis \HL \NC \NR
     \NC \infofont\meaningasis \FL \NC \NR

As you're not afraid of low level code:


     \NC $T$ \NC what \NC \NR
     \expandedloop 0 359 45 {
         \NC \number\currentloopiterator ˚ \NC \NC \NR


So, you can play with:
