Maven Exclusion for specific version

I have a project with a maven dependency that pulls in two packages, one of which pulls in a sub-dependency which is the same package of a lower version than the other. The dependency:tree looks like this:

Dependency convergence error for xerces:xercesImpl:2.10.0 paths to dependency are:
+-com.vaadin:vaadin-client-compiler:7.6.4
  +-net.sourceforge.nekohtml:nekohtml:1.9.19
     +-xerces:xercesImpl:2.10.0
and
+-com.vaadin:vaadin-client-compiler:7.6.4
  +-xerces:xercesImpl:2.11.0

The above is an output from the maven enforcer plugin where I'm enforcing dependency version convergence.

Is there a way that I can specify a version to exclude without excluding the entire sub-dependency altogether?

Declare the net.sourceforge.nekohtml dependency in your pom.xml as a first-degree dependency, and add an exclusion to it directly.

Reference: Maven Optional and Excludes

<dependency>
   <groupId>net.sourceforge.nekohtml</groupId>
   <artifactId>nekohtml</artifactId>
   <version>1.9.19</version>
   <exclusions>
      <exclusion>
        <groupId>xerces</groupId>
        <artifactId>xercesImpl</artifactId>
      </exclusion>
    </exclusions>
</dependency>
