I'd Like to know what is the proper way on removing this little piece of code on a child wordpres theme

<?php if( houzez_option('spl_con_tennant') != "" ) { ?>
                        <option value="tennant"><?php echo houzez_option('spl_con_tennant', "I'm a tennant"); ?></option>
                        <?php } ?>

How can I remove that conditional on a child theme?

the conditional is not the functions.php file
