You can override fetchall_arrayref method.

Just create dbilimit.pl 

use strict;
package DBI;

my $fetchall_arrayref;
our $ROWS_LIMIT;

INIT {
    $ROWS_LIMIT = 10;
    $fetchall_arrayref = \&fetchall_arrayref;
}

no warnings;

sub fetchall_arrayref {
    my ($sth, $slice, $max_rows) = @_;

    $max_rows = $ROWS_LIMIT
      unless defined $max_rows;

    $fetchall_arrayref->($sth, $slice, $max_rows);
}

1;

and require it after use DBI; line

P.S. the code is not tested so it may have some bugs
