External storage solution

Hi.

I need advice regarding external storage for my gigabyte aero (i7 9750h 16gb ram rtx2060) as i cant add internal nvme m2 ssd due to security caps on lid( voids warranty- already confirmed with gigabyte support). If i buy enclosure for nvme m2 and samsung 970 evo and connect taht through usb c to thunderbolt 3 port( i got 1x thunderbolt via usbc, 1x dp via usbc and 3 usb c port 3.1 gen1) i ll be able to play games like tomb rider or metro exodus without lowering performance like from internal ssd? Or installing photoshop/premiere and have similar performance?

Thank You

 

By "security caps" do you mean a "warranty void if removed" sticker? If so, those violate the law in the US and I'm sure elsewhere.
