Gigabyte aero - help needed.

Hi all.

Just bought new aero 15 laptop ( i7 9750h, rtx2060 4k oled) and got question mainly for owners of similar models:

1.how to tweak gigabyte control centre options and radiators mode correctly:

-gaming fan mode while gaming and editing videos and then manually switching to normal mode or gigabyte centre does that itself?

-same with power mode - is set to balanced. Should i switch to full performance while gaming and editing and switch back to balanced or its done automatically?
-should i switch off pantone color profile for gaming?
What else i need to set for playing with full performance on this laptop and keep it in good condition.
2. How to find out what sdd model i got? If i would like to upgrade to 1TB do i need to buy exactly same ssd or can be diffeent (model,speed) or is there any good portable ssd(thunderbolt 3 or usb 3.1) that i can install photoshop/premiere pro and games and performs like internal one without interruption, frames drop ect?
Thank You
