Ok, this is some dirty solution, but its working 😀
I found it here https://modpagespeed.com/doc/restricting_urls . This is just documentation of how you Allow or Disallow certain files/folders on your project.
So what I do is just Disallow input.js from ACF plugin
pagespeed Disallow "http://yourwebsiteurl/wp-content/plugins/advanced-custom-fields/js/input.js";
And since input.js is not going tough “fingers” of pagespeed module, everything is working fine.
