I received a new G7 7700 and the service manual says a second NVMe drive is NOT supported if it just contains a factory junk. I had to scour the internet for parts and luckily Dell had a heatsink bracket (#KKCTR for the bracket and #9JFJ7 for the screw) for less than half the price listed here. They were out of the small mount so I bought this one and it works!
