Compatibility issue with SSD?

[sysid]

Hi, i finally decided to buy an SSD (samsung 970 evo 500gb) and was making sure it's compatible with my pc but i've got this flag on pcpartpicker:
"The motherboard M.2 slot #1 shares bandwidth with SATA 6.0 Gb/s ports. When the M.2 slot is populated, two SATA 6.0 Gb/s ports are disabled."
My motherboard (asrock z170 pro4S) only has 2 SATA 6.0, so does it mean i cannot use my current HDD as secondary storage unit if i buy the SSD?

From the manual:

M.2_SSD (NGFF) Module Installation Guide
The M.2, also known as the Next Generation Form Factor (NGFF), is a small size and
versatile card edge connector that aims to replace mPCIe and mSATA. The Ultra M.2
Socket (M2_1) supports M.2 PCI Express module up to Gen3 x4 (32 Gb/s).
Please be noted that if the Ultra M.2 Socket (M2_1) is occupied by a SATA-type M.2
device, SATA3_0 and SATA3_1 will be disabled.
