Odroid N2+, Program a retry of HDMI-CEC handshake on startup?

Every time I turn on my TV and go to the HDMI input where my N2 is, my N2 starts up using HDMI-CEC. This is all good as it is set to shutdown when the TV turns off. However, to get my TV remote to work, I always have to switch HDMI input, and switch back again, for the remote to work.

It’s connected directly to my Samsung QD-OLED 90C.

Is it possible to write something in a startup script that will try to re-enable HDMI-CEC handshake after a few seconds?

Or some other ideas?
