Switch WiFI to 5GHz?

[KoalafiedDev]

I'm using a Realtek RTL8821CU Wi-Fi/Bluetooth USB dongle. The Wi-Fi is working great, but I’m having some issues with Bluetooth. When I disable Wi-Fi, Bluetooth works fine, but as soon as I enable Wi-Fi, it stops. This is because my USB dongle uses 2.4GHz for both Wi-Fi and Bluetooth. Is there a way to set the Wi-Fi adapter to use 5GHz?

Setting my router to 5GHz doesn’t fix the issue, because even when not connected to any network, simply having Wi-Fi enabled causes interference with Bluetooth. Only completely disabling Wi-Fi allows Bluetooth to function normally.
