How to install VDD under integrated graphics (iGPU)?

[UMK3614]

My laptop have a decent iGPU (Iris Xe 96EU), and I always use it because sometimes I have to use barttery power or a power bank to work, and in that situation I still need a small portable external screen, so I choose VDD.
But I've found that the VDD driver could only be installed on eGPU... A RTX 4060 laptop in case, which is a much more powerful option as I see, but it'll cost me at least additional 15W to do that (which I usually don't wanted to, my laptop's battery and my power bank are both not really big).
So I'm finding a way installing VDD under iGPU. If you brilliant guys have some ideas about this, plz tell me, I'll try anyways :-)
