On List of Supported Features in RDKB Reference Platform we see that, TR-69 is not supported on Rpi reference platform.

Does this mean, we can't use dmcli on the reference platform?
In our previous question: Does RDK-B support UCI(unified configuration interface of openwrt) or similar to UCI utility ?
it was indicated that, 'dmcli' command line utility, which will execute TR69 commands to modify the mentioned items

does No TR-69 on Reference Rpi, means, dmcli can't modify wifi related items like ssid name, ssid password etc?

Also, we see in List of Supported Features in RDKB Reference Platform :

so, without WPS how will the devices connect over wifi to a Raspberry pi running RDKB reference platform?

Also, we see :
In RDKB RPI Setup Information, we are given links to purchase TPlink Dongles:

Dongles Information Links

• For xfinity-wifi - 2g - Purchase Link - TP-LINK TL-WN823N
• For Private-wifi and xfinity-wifi - 5g - Purchase Link - TP-Link AC1300

But, both of above are Wifi Adapters, are these devices used by RDKB stack to join some other network? or to create a new hotspot ? (to which other devices will connect to)
