Can we downgrade from 19c to 12.1.0 if the compatibility is set to 12.2.0

Team:

Recently i upgraded a 12.1.0 database to 19c (non CDB architecture). Current compatibility is set to 12.2.0. Can I downgrade it to the earlier version – 12.1.0? Documentation states the downgrade is possible but am not sure about the compatibility parameter.
