Not yet, most of the RISC-V cores intended to compete with those chips are still on-paper and not in-production. Tables turn though, and the messaging ARM is sending right now seems to be directed away from their smaller piecemeal component market. That makes sense, too - Chinese manufacturers have been mass-producing knockoff ARM processors for years. There are probably more unique STM32 clones than there are unique ARM core designs available today.
The competition isn't here yet, but the bloody strangler is knocking at the door and someone upstairs just yelled "Nobody's home!"
