You should be able to hook into the admin footer and add in any kind of datepicker option as you need by field ID:

/**
 * Modify ACF Datepicker Formatted Field
 *
 * @return void
 */
function theme_prefix_admin_footer() {

	?>

		<script>

			jQuery( document ).ready( function( $ ) {
		
				let $datepicker = $( '#acf-field_5b16a9d5df47c + .hasDatepicker' );
				
				$datepicker.datepicker( 'option', {
					altFormat: 'dd. M yy'
				} );
				
			} );

		</script>

	<?php

}
add_action( 'admin_footer', 'theme_prefix_admin_footer' );
