Does the Matebook X Pro accept EXP GDC Video Card Dock (PCI-E)?
Does the Matebook X Pro have a mini PCI-E slot available to insert a EGPU cable?
A lot of people replace the wifi module in their laptop with the homemade EGPU and carry the cable outside of their laptop to the EGPU.
This product is what I would be using.
EXP GDC Beast Laptop External Independent Video Card Dock + Mini PCI-E Cable for Apple / DELL / HP / Lenovo / Asus / Hasee - Black and Grey WITHOUT POWER ADAPTER

Did you look if you can access it's wifi card?
It has a Thunderbolt 3 port, giving a faster and more convenient eGPU option.
