it's just because they haven't physically tested them. but there is no reason it won't work. they just don't want to guarantee a certain stable speed and timings without testing it first.

Corsair just specifically mentions what it has tested its RAM with, but that (sadly) is not an all-inclusive list. Not that much they have tested it with.
Personally I usually just check the motherboard QVL, which this set was not on and then just check PCPartPicker, which I found many Ryzen builds with this RAM and no complaints.

yes it may also show up as xmp which is the same thing, just change it too the speed of the ram kit and ur good to go

welcome to the forum.
all (or almost all, anyway) DDR4 ram is compatible (it will work) on the AM4 platform. you might not be able to run it at the advertised speeds, depending on your cpu and motherboard.
first, make sure to install it in slots 2 and 4 (if it's a 2x16gb kit)
then go into bios and enable DOCP (or XMP).
save and exit and it should boot.
if not, manually set dram voltage to 1.35v, enable DOCP and try again.

Should work, I see many people with this RAM + Ryzen. Even two people with this exact kit of memory + motherboard:

https://pcpartpicker.com/b/Gbq48d
 
So it should work with no issues at all. Just be sure to turn on D.O.C.P., which is a setting found I think in the 'Tweaking' section if your motherboard. Basically normally the RAM will run at 2133Mhz, but with DOCP, it can run at 3200Mhz.

you should have no issues.  what he means by tuning would be doing stuff with the clock speeds but yes u will be able to get into the bios unless the sticks are just DOA

Hello and welcome.
 
My guess is that you'll be fine.  At worst -- have to do a little tuning.
