I heard somewhere that games running in dx12 with windowed borderless will act the same with gsync as if they were running in fullscreen. I went ahead and tested this with a frame cap of 140 and vsync set too off (in game and nvcp), and there was no tearing despite my nvidia control panel being set fullscreen applications only for gsync.
I did this again with vsync enabled to get rid of the tearing on the bottom of my screen and it was gone, my question is if it's actually functioning properly and I'm not suffering from the full vsync delay.
Does gsync work in DX12 games running in windowed borderless (while gsync set to fullscreen only via nvcp)
Re: Does gsync work in DX12 games running in windowed borderless (while gsync set to fullscreen only via nvcp)
Yes, they do.
In layman's term, DX12 borderless is exclusive fullscreen + adaptive DWM.
This allows quicker alt+tabs and external overlay support, such as the system sound bar, game bar, browser windows, etc. However, whenever the game window is focused, composition disengages and it reverts to exclusive fullscreen behavior.

does Vulkan behave the same way?

It should.
To confirm, activate the NVCP G-SYNC indicator; if it shows in the same scenario as with DX12, it's working.
