Turning on VIM3 running CE

VIM3 Pro (with Khadas remote)
CoreELEC ng 20.4 (Boot from SD card).

I saw some old posts but not something that answered my question.

Looking for a way to turn on the unit through the remote instead of the side buttons.
I do have the Khadas remote, but I use a T3 remote (with IR usb adaptor).
I’m not sure if the Khadas remote operates when another one is in use, but I did try to press the power button on it and nothing happened.

Most the T3 buttons can be configured, but I didn’t find a way to get one configured to turn on the device.

Would be great if someone has an idea how to make it work on either remotes.
