How Can I Add a Type-C Port to My Computer and Drive 3 Monitors?

Jake has transitioned to a home office for his work. He has a three monitor setup for his laptop and docking station. He has another older computer that can only drive two of the monitors because it doesn't use USB-C. So he added a USB-C card. Still two monitors only. Leo says that Jake's video card is probably too old to drive all three video monitors. Are there any discreet graphics cards that can handle USB-C? Type-C can be USB 3.1 or Thunderbolt 3. Looks the same. So it can be confusing.
