Heatsink fit at this capacity
Yes. Bought with its heatsink, the Samsung 990 Pro measures 8.2mm and goes into any PS5 model with the cover closing normally. Sony's limit is 11.25mm total thickness and 25mm width (see Sony's M.2 SSD requirements).
Higher capacities are often double-sided boards. That does not change the PS5 limit, which already allows up to 2.45mm below the board, but it does matter for clip-on heatsinks with a thin base plate.
