XPS 17 9720 External G-Sync monitor

Hello,

I am looking to buy a XPS 17 9720 (12700H, RTX3060). My main usecase for this laptop is professional use for school and work, but when working at home i would like the ability to use my laptop with my 1080P 240HZ monitor for playing e-sports games.

If i enable direct dgpu outputcontroller in the bios would i be able to use my 1080 240Hz G-sync monitor through a WD19TB dock? and would G-sync function properly?

Thanks in advance!
