Disable cache for specific blocks I would like to let pages continue to benefit from Drupal 8 caching mechanism for anonymous users, except for a specific blocks which should update on every page refresh knowing that they are generated from Views.

Is it technically possible? How?
If this is a custom block, then you can use the Cache API, and set the cache max age to 0, eg

$build = [
 // ...
 '#cache' =&gt; [
   'max-age' =&gt; 0,
 ],
];


If it is an existing block, then you can alter it to add this into the render array.
