You will be able to do so when 1.2.2 wil be released.
See https://github.com/imath/buddydrive/issues/7

You’ll need to leave at least one option. But you will be able to achieve your goal when 1.2.2 will be released.

The group option needs a change event to load the user’s groups, that’s the reason why. So i advise you to keep private and group.

When 1.2.2 will be released, you’ll be able to only keep private & groups using this code :

function restrict_to_groups_private( $options = array() ) {
	foreach ( array_keys( $options ) as $key ) {
		if ( 'private' == $key || 'groups' == $key ) {
			continue;
		}
		unset( $options[ $key ] );
	}

	return $options;
}
add_filter( 'buddydrive_get_sharing_options', 'restrict_to_groups_private', 10, 1 );

see https://github.com/imath/buddydrive/issues/4

Hi this will be possible in next version (1.2.2)

You’ll then need to use this code :

function rampaaa_custom_errors( $upload_error_messages = array() ) {
	return array(
		20 => __( 'Your file need to contain the word "magic"' ),
	);
}
add_filter( 'buddydrive_get_upload_error_strings', 'rampaaa_custom_errors', 10, 1 );

function rampaaa_check_filename( $file = array() ) {
	if ( ! empty( $file['name'] ) && false === strpos( $file['name'], 'magic' ) ) {
		$file['error'] = 20;
	}

	return $file;
}
add_filter( 'buddydrive_upload_errors', 'rampaaa_check_filename', 10, 1 );

I should release 1.2.2 in a couple of days.
