Gigabyte X570 Aorus Master Preview

SATA and M.2

Sorry if this a newbie type question but do the SATA ports get turned off or "used up" if all the M.2 slots are populated. This seems to happen on some Intel motherboards, or does the new Ryzen chip have more "lanes" available and even if the board has 8 SATA and 3 M.2s you still use them all without problems?
 
The X570 chipset has dedicated support for upto 12 SATA ports afaik so a board shouldn't use any PCIe lanes for a SATA chip unless the board has 1 or more SATA ports.

Edit: Seems not, two of the 3 banks of 4xSATA ports are swappable for an extra PCIe4x4 bank so I guess for some boards there will be a trade off, but there's an extra 2 SATA ports from the CPU directly, so essentially 6 are fixed and guaranteed to not impede anything, for each further 4 SATA ports you use up 4x PCIe4 lanes.
