I was looking at the Asus Rog crosshair VII hero x470 and saw this under the m.2 section


AMD Ryzen 2nd Generation/Ryzen 1st Generation Processors
- M.2_1 Socket 3 with M Key, type 2242/2260/2280/22110 (PCIE 3.0 x4 and SATA modes) storage devices support
- M.2_2 Socket 3 with M Key, type 2242/2260/2280 (PCIE 3.0 x4) storage devices support
AMD Ryzen with Radeon Vega Graphics Processors*

- M.2_1 Socket 3 with M Key, type 2242/2260/2280/22110 (PCIE 3.0 x4 and SATA modes) storage devices support
AMD 7th Generation A-series/Athlon Processors*
- M.2_1 Socket 3 with M Key, type 2242/2260/2280/22110 (SATA mode) storage devices support

*M.2_2 is unsupported for these processors.

If i's running a Ryzen 7 2700x chip and a Vega 64 card, would I still not be able to use the M.2_2 slot specifically? Is this only not supported if I was using the cpu graphics and not a dedicated card, even though the card is Vega graphics? Any other info about this Vega graphics issue would be great too because I'm having trouble understand why that became a problem with the hardware compatibility. Thanks

The footnote is talking about the "G" processors. You have a discrete graphics card. Not applicable to the footnote.
 
Firstly your 2700X does not have an integrated graphics processor on it, so no need to. Secondly here's waht it says on the motherboard's official site

AMD 7th Generation A-Series/Athlon X4 Processors : *3
1 x M.2 Socket 3, with M key, type 2242/2260/2280/22110 storage devices support (SATA mode)
AMD X470 chipset :
AMD Ryzen™ 2nd Generation/ Ryzen™ 1st Generation Processors :

1 x M.2 Socket 3, with M key, type 2242/2260/2280/22110 storage devices support (SATA & PCIE 3.0 x 4 mode)
1 x M.2 Socket 3, with M key, type 2242/2260/2280 storage devices support (PCIE 3.0 x 4 mode)
6 x SATA 6Gb/s port(s),
AMD Athlon™ with Radeon™ Vega Graphics Processors :
Support Raid 0, 1, 10

Meaning you'll be fine using your current setup and using the M2_2 SLOT as you wish. The data from the M.2 drive will just be routed through the motherboard's onboard chipset instead of directly to the CPU itself. It won't cause any latency issues.
