No idea if this would work but…

Convert your function to a custom shortcode:

function project_excerpt() {
	global $post;
	$text = get_field('Objetivos');
	if ( $text ) {
		$text = strip_shortcodes( $text );
		$text = str_replace(']]>', ']]>>', $text);
		$text_length = strlen($text); // Get text length (characters)
		$excerpt_length = 50; // 50 desired characters
		$excerpt_more = '…';

		// Shorten the text
		$text = substr($text, 0, $excerpt_length);

		// If the text is more than 50 characters, append $excerpt_more
		if ($text_length > $excerpt_length) {
			$text .= $excerpt_more;
		}

	}
	return apply_filters('the_excerpt', $text);
}
add_shortcode('custom_acf_excerpt', 'project_excerpt');  

You can then either call it as code:
<?php echo do_shortcode("[custom_acf_excerpt]"); ?>

Or as a shortcode in the editor:
[custom_acf_excerpt]

Code is untested
