How can I get 120hz 4k to run on my LG CX from my 2021 Razer Blade 15 360hz 3080 laptop going through my Thunderbolt 3 Dock?

LG CX HDMI > Anker Thunderbolt 3 dock > Thunderbolt Port

Contrary to almost all my "research", It can be done, because I just exchanged this exact model and I was able to get it to work before hand, again same exact model with the exact same setup. I was even able to get it to work on a 19' RB15 2070, which I originally had.

Seemingly, I just can't get my computer's 3080 to want to pick up this physical thunderbolt connection at all, it only connects to Intels iGPU. On the prior computers, normally the dGpu would instantly recognize the external display and I would just have to adjust color format to YCbCr 4:2:0 to get 120hz at 4k.

Any help would be greatly appreciated, I've spent an absurd amount of troubleshooting time on this, and spent top dollar to have a clean simple setup, which couldn't be further from the case right now.
