Hi, advise is needed as I'm confused.

I have a ASRock Z370 MoBo currently installed 3xM2 NVMe SSDs (according to BIOS all in PCIe mode). Motherboard has also 8 SATA ports, some of which I would like to utilize. However I'm confused which SATA ports will be disable in such config.

So according to the manual:
"M2_1, SATA3_0 and SATA3_1 share lanes. If either one of them is in use, the others will be disabled."
"M2_2, SATA3_4 and SATA3_5 share lanes. If either one of them is in use, the others will be disabled."
"If M2_3 is occupied by a SATA-type M.2 device, SATA3_3 will be disabled."

Do I understand it right - that I can use 3 SATA ports: SATA3_2, SATA3_6 and SATA3_7?
