Power delivery over 2 thunderbolt ports?

Just recently picked up the HP Spectre x360 15 (Core i7-8750H, GTX 1050 Ti Max-Q) and it comes with 2 thunderbolt ports on it.

Can you get power delivery from 2 different thunderbolt ports at the same time? 

Planning to use the laptop with an Oculus Rift, eGPU enclosure and a USB hub but I am not sure about the power delivery and if I should factor that into my decision on picking an eGPU enclosure and hub. The laptop is speced at 135w but it appears thunderbolt is limited to 100w. If I get an eGPU hub with 100w and a USB hub with 60w power delivery would that cover the 135w the laptop can pull?

Laptop > HP Spectre x360 15 (Core i7-8750H, GTX 1050 Ti Max-Q, 512 GB NVMe, 4K)
eGPU > TBD (Razer Core X, Asus XG Station Pro, AKiTiO Node?)
GPU > GTX 970
Thunderbolt USB hub > TBD (Sendcool - USB C Hub 8 in 1 - Type C Hub with Ethernet Port, 3 USB 3.0 Ports, SD/TF Card Reader, 4K USB C to HDMI, USB C Power Delivery 87W?)

The power management of your system would opt for the source with higher power delivery. In the example you propose it would be 100W PD from the capable eGPU enclosure. That amount should suffice for most scenarios except for when you run the laptop full load for an extended time.
