Dell 9560 Dual 4k 60 fps possible?

Dell 9560 running OpenCore Hackintosh Ventura, and Windows 11 (dual boot)

Thunderbolt 3 only has two lanes on this laptop. I'm wondering if connecting an eGPU -> TB3 output, then eGPU -> dual 4k 60fps.

Is it possible?

FYI: I do NOT want to use DisplayLink Manager ( introduces lag ),

Have already tried mutliple docks including Dell docks. None worked. The limitation is in the TB3 port itself - IE only two lanes.

Please only respond if you know what you are talking about.
