How to add multiple 'orderby' in functions.php

Hello, i have custom fields, but in the following function all posts that don’t have custom field ‘podredba’, are not displayed.

function category_archive_sort_posts($query) {
  if ( !is_admin() && $query->is_main_query() ) {
    if ( is_category( 1192 ) ) {
      $query->set( 'orderby', 'meta_value_num' );
      $query->set( 'meta_key', 'podredba' );
      $query->set( 'order', 'ASC' );
    }
  }
}

add_action('pre_get_posts','category_archive_sort_posts');

How can i merge the following two codes in one?

$query->set( 'orderby', 'meta_value_num' );
$query->set( 'meta_key', 'podredba' );
$query->set( 'order', 'ASC' );

with

$query->set( 'orderby', 'date' );
$query->set( 'order', 'ASC' );
