Enqueue Fonts with theme.json but disable the Font Family UI in the Block Editor

[silaskoehler]

I like the opportunity to load the fonts via theme.json. However, when I do that, I always have the UI for it in the editor and I don't want that. My current solution is to load the fonts via the theme.json and then set the block support for __experimentalFontFamily to false via the register_block_type_args.

add_filter('register_block_type_args', 'deinprefix_filter_block_supports_', 10, 2);
function deinprefix_filter_block_supports_($args, $block_type) {
	if (isset($args['supports']['typography'])) {
		$args['supports']['typography']['fontSize'] = false;
		$args['supports']['typography']['__experimentalFontFamily'] = false;
	}
	return $args;
}

Is there a better solution? I use a classic or hybrid theme and would prefer to load the fonts via php.
