As far as I can tell, it's not possible to set SLF4J's logging level at runtime.
You could try using these startup flags to suppress logs from "com.zaxxer.hikari".

However, I've spent a good ~20 mins testing and can't get it to work for me.
Either way, this isn't really an LP issue. More of an issue with Forge's logging setup. (you'll notice that these entries do not get sent to the console.)
You need to override FML configuration https://github.com/MinecraftForge/FML/blob/master/src/main/resources/log4j2.xml by copying it to your launch folder,
then adding a specific logger for HikariCP at error level
...
<logger name="com.zaxxer.hikari">
<level value="error"/>
</logger>
...
and forcing your custom configuration file through your launcher parameter
-Dlog4j.configurationFile=log4j2.xml
This is as explained briefly on FML and SpongeCommon issues here: MinecraftForge/MinecraftForge#1643
and there: SpongePowered/Sponge#281
Not sure how that would be possible in LuckPerms? I just download the Hikari jar and load it. How would the logger implementation know to read from a file in the LP jar?
