Remove standard meta boxes from custom taxonomy

Question

I registered a custom post type, and then registered a taxonomy to show on the custom post type. When clicking on the taxonomy entry on the post type, I see the edit screen with various native boxes, aka:

Name
Slug
Parent Item
Description

Since I will use ACF exclusively, there is no need to display the description box, or Parent Item box.

Is there a way to remove them? (without using the css display property)

Thank you for any pointers.

Unfortunately not. These items are hard-coded into the wp-admin/edit-tags.php file. The best route is the route you didn't want to go which is CSS.

You can replace category in the below array with a list of taxonomies you want to apply these styles to. The function checks the current taxonomy against this array and if it's found will apply the CSS styles to hide these fields.

/**
 * Hide taxonomy fields per taxonomy
 *
 * @return void
 */
function wpse344725_taxonomy_css() {

    global $taxonomy;

    $modified_tax_arr = array( 'category' );

    if( empty( $taxonomy ) || ! in_array( $taxonomy, $modified_tax_arr ) ) {
        return;
    }

    ?>

        <style>
            .form-field.term-slug-wrap,
            .form-field.term-parent-wrap,
            .form-field.term-description-wrap   {display: none;}
        </style>

    <?php

}
add_action( 'admin_head', 'wpse344725_taxonomy_css' );

Additionally, with the above method you could remove them with JavaScript or hide them with any other CSS visibility property. I can't think of a reason why you wouldn't want to simply hide them in CSS maybe with more elaboration we can find a better solution.
