However when I scan for these endpoints on my desktop using a AR93xx Wireless Network Adapter from Qualcomm, while it is able to see the 2.4GHz network fine it cannot see the 5GHz one at all.
Why would this be so? It does see other 5Ghz networks in the area:

Both Bands 2,4GHz and 5GHz use a set of "channels" to communicate with devices.
Your router is using channel 108 for 5GHz.
- Try to find out which channels your wireless card supports:
How to find supported wireless channels
iwlist wlo1 freq- Try to change the router`s channel for 5GHz(from the router admin interface) from 108 to a supported channel (eg 44 as the displayed network)
As a reference, what are Wifi channels
WiFi channels are smaller bands within WiFi frequency bands that are used by your wireless network to send and receive data. Depending on which frequency band your router is using, you have a certain number of WiFi channels to choose from:
- 11 WiFi channels are in the 2.4 GHz frequency band
- 45 WiFi channels are in the 5 GHz frequency band
