ADR (adaptive datarate)

I have a conduit with fw 1.3.2 and 2 adeunis rf lora transmitter.

The communication works. After the first 4-6 messages from the transmitters (with SF12) the conduit sent a command to decrease the datarate. I saw this in the lora-network-server logfile. Now the transmitters are sending with SF7.

Is it possible to send a command to the transmitters to increase the datarate to SF12?

Thanks!
