Not sure what part you are having trouble with but try this

#!/usr/bin/perl
use strict;
use warnings;
use File::stat;
use Text::CSV_XS;
my $csv = Text::CSV_XS->new(
  { binary => 1, eol => $/ }
);

my $ONE_DAY = 86400;
my $Foutput = "data0426-2.csv";
open my $out, ">", $Foutput or die "$!";

# create array of csv filenames in directory
my $dirname = "Daily_QoS_CPD_link";
unless (-d $dirname) { 
  die "Not able to open $dirname";
}
my @dir = glob "$dirname/*.csv";
   
# parse files modifed in past 24 hours  
foreach my $infile (@dir){
    
  my $age = time()-stat($infile)->mtime;
  if( $age < $ONE_DAY ){  
    open my $FH, "<", $infile or die "Could not open $infile : $!";
    while (my $row = $csv->getline($FH)) {
      if ( $row->[2] =~ /^(DROPPED-10|CALL_START|CALL_END)$/ ) {
        $csv->print($out, $row);
      }
    }
    close $FH;      
  }
}
