Can I have LBT protocol on DEVO10 radio

I have an old DEVO10 radio. I am wondering whether it is possible to install the LBT (listen before transmit) protocol as required for operation in Europe.
Are firmware versions available using the "deviation" system, or are these produced by Walkera ?
Can I also reprogram a Devention receiver for this protocol ? Or should I use LBT-activated FrSky receivers ?

You need to install a 4in1 module and then update your radio with the latest nightly build of DeviationTX. It works fine. I have just sold my Devo10 but used it on my FrSky X8's that had EU-LBT
