G’day mate,

The proper function you are looking for to add/edit a entry to the repeater field is called update_row.
https://www.advancedcustomfields.com/resources/update_row/

And, the proper hook you are looking for is acf/save_post, which gets triggered after the entered acf values are saved.
https://www.advancedcustomfields.com/resources/acf-save_post/

To combine the above 2 resources, your code should look something similar like:

add_action('acf/save_post', 'insert_that_very_special_row');
function insert_that_very_special_row($post_id) {
	// get how many rows is already in the database first, 
	// cause we need to insert our row by index
	$row_count = count(get_field('attributes_cargo_pick', $post_id)?: []);

	// the new row that we wanna add
	$row = ['pcs' => 1, 'bol' => 2, 'size' => 3];

	// update it as the next index (++$row_count)
	update_row('attributes_cargo_pick', ++$row_count, $row, $post_id);
}

Cheers 😬
