@morgan-estes Great solution but it i think it should be better to add_filter in else so the next block or content gets filter with WPAUTOP
/**
* Try to disable wpautop inside specific blocks.
*
* @link https://wordpress.stackexchange.com/q/321662/26317
*
* @param string $block_content The HTML generated for the block.
* @param array $block The block.
*/
add_filter( 'render_block', function ( $block_content, $block ) {
if ( 'acf/featured-pages' === $block['blockName'] ) {
remove_filter( 'the_content', 'wpautop' );
} elseif ( ! has_filter( 'the_content', 'wpautop' ) ) {
add_filter( 'the_content', 'wpautop' );
}
return $block_content;
}, 10, 2 );
