The reference site for the Wireshark source code is currently here.
The nr-rrc dissector is an "asn1" dissector where the main protocol definition is in one or more .asn files which are combined with the .cnf and packet-xxx-template.[c|h] files to produce a C dissector, in this case packet-nr-rrc.c.
If you search that file you will find lots of references to RadioBearerConfig which may help you find what you're looking for.
