Is it possible to replace the laptop's external graphics card PCI-E with the Thunderbolt 3 socket?

  It is unrealistic to change the laptop's external graphics card interface from a PCI-E interface to a Thunderbolt 3 interface.
  The PCI-E interface and the Thunderbolt 3 interface have different communication methods and supported data transmission methods, so their interfaces and circuit designs are also different. Generally speaking, the PCI-E interface is used to connect graphics cards and expansion cards plugged directly into the motherboard, while Thunderbolt 3 can be used to connect external GPU memory, external graphics cards, and other peripherals.

  Although some companies have manufactured external graphics card docking stations that support the Thunderbolt 3 interface, since the external graphics card uses a PCI-E interface, in this case, a PCI-E adapter is still required inside the docking station.
  In summary, due to the differences between the PCI-E interface and the Thunderbolt 3 interface, as well as the conversion and compatibility issues of hardware and software that need to be supported when using an external graphics card, it is necessary to change the external graphics card interface of the laptop from the PCI-E interface. Changing to a Thunderbolt 3 interface is usually unrealistic.
  Generally speaking, the PCI-E interface of the laptop is incompatible with the Thunderbolt 3 interface, so the external graphics card PCI-E cannot be directly converted to Thunderbolt 3 form. However, some specific models of laptops may support the use of external graphics cards, so you need to carefully read the manual of your laptop or consult the manufacturer. At the same time, you also need to purchase a special external adapter box to connect the external graphics card to the Thunderbolt 3 interface. Additionally, you'll want to make sure your laptop supports Thunderbolt 3 and has enough power to drive an external graphics card.
