Can someone quickly mark the places where you can mount the SSD with a screenshot and share it here with a link?

Exactly as others have already said: 4x NVMe x4 and 4x SATA 6GB/s !
That's exactly how many I actually have connected. see my screenshot here:

The board has the advantage of only supporting PCI 5.0 in the graphics card slot and not also in the "first NVMe slot", as otherwise there may be a drop in bandwidth due to "too few lanes". Just read the whole posted thread. This is generally a topic for mainboards with two PCI 5.0 slots.

SSDs no longer have a fixed disc, otherwise they would not be SSDs. Then there is the question of whether you mean an M.2 SSD or a 2.5" SSD via SATA. M.2 you get 3 pieces (NOT 4! Description is wrong) on the mainboard. SATA connections I meant the thing has 6 (NOT 4! Description is also wrong here). I gave the mainboard in my PC.

The description says 4x M 2.0 SSD and 4 x Sata SSD or HDD.
