Try this:

add_filter('request', function( array $query_vars ) {
    if ( is_admin() ) {
        return $query_vars;
    }

    $targets = array(
        'My name here',
        'Another',
        'One More Name',
    );

    if ( isset( $query_vars['category_name'] ) && in_array( $query_vars['category_name'], $targets ) ) {
        $pagename = $query_vars['category_name'];

        $query_vars = array( 'pagename' => "$pagename" );
    }

    return $query_vars;
} );

Then adjust the names of the categories you want to target in the $targets array.
