can you get 8khz polling rate with the mouse dock pro?

I'm planning on upgrading from my logitech G502 hero to the razer basilisk V3 pro 35k. I wanted something wireless + a higher polling rate than 1000 hz, and it's what people recommended. I've been looking around online, and some sources say you can only get 4khz polling with the mouse dock pro, and others say you can get 8khz with it. If only 4khz is possible, I'll buy the hyperpolling dongle instead of the dock, but the dock has the added benefit of wireless charging which is convenient to me because I am not great at cable management in my setup (it's a mess). Can someone who has a mouse dock pro with up-to-date firmware tell me what's the max polling rate they can get with their mouse?
