Garmin Edge 530 + Xert

Hello, I am quite new to the world of Xert.
Unfortunately, my trainer is not fully compatible with the Xert EBC Android application, so I am forced to use Garmin as a device.

Is it possible to set Garmin to turn on the backlight only when the interval value is changed?

You can change the backlight settings on the Garmin but not within the Connect IQ app.
What model trainer? Is it ANT+ only?

Yep i know that i can change backlighr on Garmin settings, but it would be greate if screen will turn on when interval is going to change.

My trainer is Tacx T2240 i was on contact with support on this case.
