Will connecting a DisplayPort or HDMI cable through my USB-C (Thunderbolt 3) force my laptop to use my dedicated GPU and output at a higher refresh rate?

I have a Lenovo 720s with a Geforce MX150 and Intel UHD Graphics 620. My 3440x1440 monitor supports up to 144hz and the laptop has a HDMI 1.4b port which supports up to 60hz at 3440x1440 resolution, but I'm only getting 30hz. I believe its the integrated graphics that is the limiting factor.

I want to purchase a USB-C to HDMI 2.1 or to DisplayPort 1.4 adaptor. Unless going to high bandwidth is an issue and I should stick to HDMI 1.4 or DisplayPort 1.2??

I don't game much on my PC, I really just want to use the Citra emulator @60hz and I have a three month xbox cloud gaming trial I want to try out. It would also be nice to be able to get 60hz on youtube videos.

Thinking of getting something like this HDMI adaptor or this USB-C to DisplayPort cable
