AashutoshNP, I have not heard of any information about adding a mux switch to the G15 5511 systems.
I bought the Dell g15 5511 i5-11400H 3050ti 6 months ago  Later i realized there is no mux switch available. Is there any possibility or work in progress to add mux switches to intel chip laptops for the g series?
