That should probably be GlobalKnownHostsFile, not UserKnownHostsFile.
>From the the ssh_config(5) man page at
https://manpages.debian.org/bullseye/openssh-client/ssh_config.5.en.html
:

GlobalKnownHostsFile

    Specifies one or more files to use for the global
    host key database, separated by whitespace.
    The default is /etc/ssh/ssh_known_hosts,
    /etc/ssh/ssh_known_hosts2.

But not setting GlobalKnownHostsFile gets you the default, which
appears to be the same as you specified in your config file.
