add_filter( 'redirect_canonical', function( $redirect_url ) {
	$posts_with_pagination = [ 1, 2, 3, 4 ]; // array of posts that have custom pagination.
	if ( is_paged() && in_array( get_the_ID(), $posts_with_pagination ) ) {
		return false;
	}
	return $redirect_url;
} );

This example shows how to allow standard pagination on singular posts for specific posts. If you want to target a whole post type or other, please modify accordingly.
