My previous post has been removed / deleted so I thought I'd post this if anybody should be curious / find this info helpful:
The ASUS GU502GV
(i7-9750H / RTX 2060) USB-C / DP-Port
seems to be "hard-wired" to the RTX 2060
, after all (see screenshot attached).
Still experiencing the tracking-judder but I guess I'll have to troubleshoot / dig further to resolve this.
