nvme installation and if sata ports will be disabled or loose performance of nvme?

[frozen_sun]

I've purchased 970 evo plus and want to install it.
Since I have used 5 of sata ports (3 HDD,1 SSD and 1 for optical DVD-ROM) I need to know if any of those ports will be disabled,or if I will loose full performance of the nvme since those sata devices are installed?
I'm not sure which port uses above devices,but I used 5 of them.

I've read manual here it says:
the m.2 shares bandwith with SATA Express 1 Slot.
I have some devices hooked up on SATA Express slots but not the first 2 on the left side (downside) of the board.
The first 2 sata ports near U2 port are free.Is that where Sata Express 1 slot is located?
I can't seem to find Sata Express 1 Slot it's not marked on motherboard.

In my VIII Hero's manual, I think it's marked on the mobo diagram.
