[UK] Razer Blade 15 Advanced 2021 questions

Hi Razer Support, I've recently made an order for a RB 15 2021 Advanced 240hz QHD RTX 2080 32GB RAM 1TB SSD model.

As this was purchased in the UK, I wanted to ask some things which were not clear from ordering:

1. Is this just primary key backlighting or has this now been updated to also do secondary in UK? Previously It appeared you had to buy in US to get secondary key backlighting.

2. There is no mention of G-Sync or advanced Optimus on the website, but I believe the 240hz QHD model (from press/reviews) has G-Sync and advanced Optimus. Could you confirm this is the case in UK?

3. Do you use optical switches on the keyboards? No mention of these anywhere.

Many thanks
