In XSLT 2.0 you can copy an element without copying its namespaces using the
copy-namespaces="no" attribute.

In XSLT 1.0 the answer is no. xsl:copy-of copies a tree unchanged, which
includes its namespace nodes (remember that in the data model, an element
has namespace nodes corresponding to all in-scope namespaces, including
those declared on ancestor elements). You only remedy is not to use
xsl:copy-of, but to do a manual copy using a modified identity template:

<xsl:template match="*">
  <xsl:element name="{name()}" namespace="{namespace-uri()}">
  <xsl:copy-of select="@*"/>
  <xsl:apply-templates/>
  </xsl:element>
</xsl:template>
