Bluetooth nopt working

I am trying to enable Bluetooth but cannot get it working.

I am on DietPi v9.11.2

I have the following BT card installed: Amazon.com: Orange Pi 5 Plus WiFi 6 Module Wireless Card 1201Mbps PCIe Wi-Fi6+BT5.2, Wireless Module R6 Support WiFi Bluetooth Compatible with Orange Pi 5 Plus Singble Board Computers : Electronics

I have enabled BT via dietpi-config.

Running bluetoothctl I get the following:

bluetoothctl
Agent registered
[bluetooth]# scan on
No default controller available
[bluetooth]# 

Running systemctl start hciuar I get the following:

Failed to start hciuar.service: Unit hciuar.service not found.

Not sure where to go from here… Any help is appreciated.
