No TB5, in 2024?

So I am thinking about getting this MB (Upgrading from a Hero VIII x570) and cant seem to find the answer to the one question holding me back. If I populate all 4 nvme slots and put a card in the x4 slot for another nvme will it cut down my main PCIe to x8 or disable sata ports?

Appreciate the day one review and it seems like the X870E is the way to go for people hopping on the platform even if it isn't enough of an upgrade for those already on X670E. I'm curious if memory topologies have changed at all or if the higher support listed is due to AGESA optimization.

MSI's specifications show the second slot is limited to x4:
3x PCI-E x16 slot
PCI_E1 Gen PCIe 5.0 supports up to x16 (From CPU)
PCI_E2 Gen PCIe 5.0 supports up to x4 (From CPU)
PCI_E3 Gen PCIe 4.0 supports up to x4 (From Chipset)

It would be helpful to note when there are M.2 restrictions as well since populating M.2_2 will cause the primary PCIe slot to run x8:
4x M.2
M.2_1 Source (From CPU) supports up to PCIe 5.0 x4 , supports 2280/2260 devices
M.2_2 Source (From CPU) supports up to PCIe 5.0 x4 , supports 2280/2260 devices
M.2_3 Source (From Chipset) supports up to PCIe 4.0 x4 , supports 22110/2280 devices
M.2_4 Source (From Chipset) supports up to PCIe 4.0 x4 , supports 2280/2260 devices
4x SATA 6G

* PCI_E1 & PCI_E2 & M.2_2 share the bandwidth, and PCIe version support varies depending on the CPU.

Yes, all 8-series am5 use it "Intel lga 1700 style":
PCI_E1 & PCI_E2 & M.2_2 share the bandwidth, and PCIe version support varies depending on the CPU. Please refer to the PCIe configuration table in the manual for more details.

Choice 6-series soc instead

Seems like a great board but wow are they becoming expensive.
