Is there anyway to force all traffic except Maven Central via Internal Repo?

So, I have a requirement to force all requests to Maven Central via CodeArtifacts, while all other traffic to Nexus repository hosted by organization. My settings.xml looks like below

<mirrors>
 <mirror>
   <id>aws-codeartifact</id>
   <mirrorOf>central</mirrorOf>
   <name>CodeArtifact mirror for Maven Central only</name>
   <url>https://abc-code-artifacts.d.codeartifact.us-east-1.amazonaws.com/maven/maven-test-repo/</url>
 </mirror> 
    
 <mirror>
   <id>abc-nexus</id>
   <mirrorOf>*,!aws-codeartifact</mirrorOf>
   <name>Nexus Group for everything else</name>
   <url>https://nexus.abc.com/repository/repository/maven-group/</url>
</mirror>       

Now the issue, is this doesn't work. It results in all requests to be pulled via my Nexus repo,as if "*" over-rides everything

My requirement is to :

• Ignore any repositories configured in project pom.xml (Above settings.xml goes in to CI/CD Tool)
• Mirror Public Repository requests alone to CodeArtifacts, but everything else via Nexus.

Is this an expected behavior, or is there any work around?

<mirrors>
    <mirror>
      <id>internal-repo</id>
      <mirrorOf>*,!central</mirrorOf>
      <url>https://your.internal.repo/repository/mirror/</url>
    </mirror>
  </mirrors>
