There is a issue with card about waking up during boot and from suspend the only way to prevent it (is seems) by making pci_ps = false, on Acer Swift 3 (ryzen 2500u).
Can you provide dmesg output when this problem happens? Was QCA6174 installed to Swift 3 by default at the factory or did you install it afterwards on your own?

This increases power consumption for all QCA6174 devices so I'm not eager to do this. -- https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
