In a freestanding environment on ARM64, running with LLVM's UB sanitizers will result in a `brk` instruction with a particular encoding that contains the reason UB was detected. Unfortunately, on RISC-V UBSAN just emits an unimp instruction and from what I can tell there's no way to get further information as to *why* UB was detected.
