No. If an I3C Slave will be used only on I3C Buses that rely on the SETAASA CCC (which auto-sets the Slave’s Dynamic Address from its I2C Static Address) and/or the SETDASA CCC (where the Master sets the Slave’s Dynamic Address using a Direct CCC that references its I2C static address), then that Slave would never be asked to use DAA and could participate on the I3C Bus without implementing DAA. However, MIPI Alliance strongly recommends supporting the DAA (ENTDAA) approach as well, otherwise the Device will only ever be usable on that narrow subset of I3C Buses.
