Module nf_conntrack is loaded but an error persists

Hello,
When I boot my RHEL 9.2 s390x system, it logs the following error :

Error running install command '/sbin/modprobe --ignore-install nf_conntrack && /sbin/sysctl --quiet --pattern 'net[.]netfilter[.]nf_conntrack.*' --system' for module nf_conntrack: retcode 127

lsmod shows that the module is loaded. Besides, firewalld is running without error.

Is there a way to suppress this message ?

Regards.
