Does it specifically have to be 802.11ac ?
I just grabbed a dongle that is 802.11n that I normally use only on a Raspberry Pi and plugged it in to a normal computer with a standard Linux kernel (NB: Not Purism hardware, not running PureOS, is in the Debian family though) and I believe that this computer has never seen that model of dongle before and it worked out of the box.
syslog muttered something about
Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter.
I think you will generally go fairly well with Realtek on Linux.
Your Amazon link is even claiming that Linux works. The only way to know for sure is to buy it and try it out. Heck, I placed an Amazon order just the other day. I should have added one to my order. I think my fairly old AP doesn’t do 802.11ac though so I could only have tested at best that the dongle falls back to 802.11n correctly.
