Disable browser upload of media option for site users

I tested the below code in my functions.php and so far everything works great.

<?php
/**
 * Limit file upload size for all upload methods (browser and multi-file uploader)
 * This works by intercepting uploads before they're processed
 */

// Set the maximum file size limit (in bytes)
function seiu_get_max_upload_size() {
    return 180 * 1024; // 180 KB in bytes
}

/**
 * Check file size before upload and reject if too large
 * This works for ALL upload methods including browser uploader
 */
function seiu_limit_upload_size_prefilter( $file ) {
    $max_size = seiu_get_max_upload_size();
    
    // Check if file size exceeds limit
    if ( $file['size'] > $max_size ) {
        $max_size_mb = round( $max_size / 1024 / 1024, 2 );
        $file_size_mb = round( $file['size'] / 1024 / 1024, 2 );
        
        $file['error'] = sprintf(
            'File size is too large. Maximum allowed size is %s KB (%s MB). Your file is %s MB.',
            number_format( $max_size / 1024 ),
            $max_size_mb,
            $file_size_mb
        );
    }
    
    return $file;
}
add_filter( 'wp_handle_upload_prefilter', 'seiu_limit_upload_size_prefilter' );

/**
 * Also keep your existing filter for the upload_size_limit
 * This affects the JavaScript uploader size checking
 */
function seiu_limit_upload_file_size( $size ) {
    return seiu_get_max_upload_size();
}
add_filter( 'upload_size_limit', 'seiu_limit_upload_file_size', 20 );

/**
 * Optional: Modify the upload size limit text shown in Media Library
 */
function seiu_upload_size_limit_text( $content ) {
    $max_size = seiu_get_max_upload_size();
    $max_size_kb = round( $max_size / 1024 );
    
    return sprintf(

            var maxSize = <?php echo $max_size; ?>;
