Tell nagios not to warn about non-critical updates

I use nagios to warn if there are apt updates available on my Debian buster server, but I want to use this option: -o, --only-critical Only warn about upgrades matching the critical list. The total number of upgrades will be printed, but any non-critical upgrades will not cause the plugin to return WARNING status. so I edited /etc/nagios-plugins/config/apt.cfg: # 'check_apt' command definition define command{ command_name check_apt command_line /usr/lib/nagios/plugins/check_apt --only-critical } # 'check_apt_distupgrade' command definition define command{ command_name check_apt_distupgrade command_line /usr/lib/nagios/plugins/check_apt --only-critical -d } But still I get emails containing something like:

***** Service Monitoring on freifunk *****

apt on vm02.freifunk is WARNING!

Info:    APT WARNING: 2 packages available for upgrade (0 critical updates).

Although I have installed monitoring-plugins-basic 2.2-6 and the --only-critical option was added in release-2.3.3 it is working already:

# /usr/lib/nagios/plugins/check_apt
APT WARNING: 2 packages available for upgrade (0 critical updates). |available_upgrades=2;;;0 critical_updates=0;;;0
# /usr/lib/nagios/plugins/check_apt --only-critical
APT OK: 2 packages available for upgrade (0 critical updates). |available_upgrades=2;;;0 critical_updates=0;;;0

But the command option I set in the nagios config seems to be ignored. I also tried the latest version manually installed from this source , but it didn't change the outcome. Maybe is there another way to achieve this? maybe just change the line in command_line to something, that greps the result somehow? it seems like the nagios plugins are used by icinga2. This is a part of /etc/icinga2/constants.conf: /* The directory which contains the plugins from the Monitoring Plugins project. */ const PluginDir = "/usr/lib/nagios/plugins" How do I properly tell nagios not to warn about non-critical updates?
