No. It doesn't support external GPUs. It must have a “Thunderbolt” port, which supports higher bandwidth as well. A thunderbolt uses 2 or 4 PCI express lanes so it can enable the access of external GPU to the processor.
Apart from that, just for a different example, even USB Type C doesn't support external GPUs.
The port hardware doesn’t have the capability to do that…One needs thunderbolt hardware support for this…..You need to look at the PCIe bandwidth to run a GPU. USB Type C Gen2 doesn't give any PCIe lanes, which will make running a GPU pretty much impossible. Even Thunderbolt 3, which gives PCIe Gen3 x4 bandwidth, will bottleneck a GPU. For a GPU, you want at least PCIe x8.
BTW, even Even Thunderbolt 3 bottlenecks external GPUs due to bandwidth problems, if I'm not mistaken. The usb type-c port must support thunderbolt-3 for any of the external GPU docks to function, due to the bandwidth thunderbolt-3 provides.
