Remove date stamps in SERP

Hi,

for removing the date stamps in SERP in search engines like Google completely I added the following code to functions.php:

function jl_remove_post_dates() {
        add_filter('the_date', '__return_false');
        add_filter('the_time', '__return_false');
        add_filter('the_modified_date', '__return_false');
        add_filter('get_the_date', '__return_false');
        add_filter('get_the_time', '__return_false');
        add_filter('get_the_modified_date', '__return_false');
} add_action('loop_start', 'jl_remove_post_dates');

Unfortunately this is removing all visible dates in magazine elements, latest news, single post etc. But what I want to achieve is to remove the dates of posts in SERP only.

I read that it could be helpful to remove the word “published” in time classes of functions.php for not showing up a date in SERP (but “updated” should not be removed). But I am not quite sure.

What do you think? Do you have an idea how to remove (without a plugin or similar)? Would be great!

Thank you and best regards,
Sophie
