Which log are you talking about? It sounds like events.log. You can’t change what gets logged there from the binding because that’s not what’s logging there. That log contains all the events published to the event bus.
See How to watch and look through logging and openHAB - Filtering event logs.
If you set up a filter, you’ll have to translate that to XML. Here’s an example filter.
<RegexFilter regex=".*createTimer.*deprecated.*" onMatch="DENY" onMismatch="NEUTRAL"/>
You’ll have to adjust the regex and add that to the Event log appender.
Note, I’m of the opinion that either the events.log is useful or it isn’t. If it isn’t useful, disable it. If it is useful, its counter productive to redact it and hide some of what’s going on. There are lots of ways to filter logs on the fly (you can even do so in FronTail) to only see those lines you care about at that time without excluding them from the logs entirely.
