8tb NVMe upgrade for Razer Advanced Model 15 2021

Hi there! I have a Razer Laptop (advanced model 15 2021, RZ09-0367C1C3) and I´d like to know if I can install a  8tb NVDMe , in particular this one, which is at a very good price in amazon (WD_BLACK 8TB SN850P NVMe M.2 SSD Officially Licensed Storage Expansion for PS5 Consoles, up to 7200MB/s, with heatsink - WDBBYV0080BNC-WRSN) Would it be compatible? How many can I install, appart from the one with the OS (windows 11)? Just one I guess? or more? Is there room for that big heatsink? Do I need it? Thanks!!
