Hiding non-member message in cart and checkout

I want to hide the message that displays for non-members in my cart and checkout:

This item is discounted for members. Log in to claim it.

I found this code in class-wc-memberships-frontend.php:

/**
    * Get member login message
    *
    * @since 1.0.0
    * @return string
    */
    public function get_member_login_message() {

    if ( count( $this->get_cart_items_with_member_discounts() ) > 1 ) {
    $message = __( 'Some items in you cart are discounted for members. %sLog in%s to claim them.' );
    } else if ( count( WC()->cart->get_cart() ) > 1 ) {
    $message = __( "An item in your cart is discounted for members. %sLog in%s to claim it." );
    } else {
    $message = __( "This item is discounted for members. %sLog in%s to claim it." );
    }

    return $message;
    }

Can I hide it using my child theme functions.php?
