@Hasan101101 You might be able to use this snippet. You can control the size of the image that WordPress core fetch is getting applied to.

add_filter( 'wp_min_priority_img_pixels', function( $size ) { return 1000000; } );

FYI, we have WordPress core fetch disabled on all of our sites. The way it was implanted into WordPress core is not great. That's also why we added fetch into our plugin. https://perfmatters.io/docs/fetch-priority/ This way you can target anything you want. Although I usually recommend using a preload over fetch. But it depends on the site.
