Tvheadend

Hi!
I'm running Tvheadend 4.2, with coreelec 9.2.1 on a setup box

I was looking for a way to disable channels if tvheadend detects there is no signal for them (for example, I have configured both direct cable and IPTV for some channels, but some of them only work with the antenna and can't be seen without it)

When watching the tvheadend web (port 9981) I can see the log detecting when it receives no signal from a channel. Is there any way to detect this and temporarily disable the channel, through some script, until it gets signal again/until next time tvheadend is rebooted?

Thank you in advance for the answers.
