I ended up making it work myself. Here is what I did:

In the functions.php I add this code, to block the Facebook Pixel:

<?php
//Disable facebook
function disableStuff() {
    return true;
}
add_filter('pys_disable_facebook_by_gdpr','disableStuff');
?>

Then, in my header, I insert the following script, that runs when the user is giving consent, and also on page load, checking if the user have consented. I then use the utility function I found on the pys object, to activate the Facebook Pixel on consent:

window.addEventListener('CookieInformationConsentGiven', function (event) {
if (CookieInformation.getConsentGivenFor('cookie_cat_marketing')) {

//Activate the pixel when the page is loaded
    window.onload = function() {pys.Facebook.loadPixel();};

//If the page is already loaded, and the user gives consent, activate the pixel
if(typeof pys !== 'undefined') {
    pys.Facebook.loadPixel();
}
}}, false);

I am posting this, in the hopes that it will help other devs in my position. Please flesh out your docs for devs, PixelYourSite. You plugin is awesome.
