[Users] changing log level of certain messages

[Dimo]

Hi guys,
I was wondering if it is possible to change the log level of some
messages, namely:
ERROR:auth_radius:radius_authorize_sterman: rc_auth failed
 rc_send_server: no reply from RADIUS server xxxx.:1812

I have alot of clutter from this one and i would like to lower its
severity so it does not get logged, but i still need other messages
from radius to be logged.
Apart from going into the code and changing the log level do you know
of any other way to do it?

Best.
Dimo
