Is there some way to disable the bluetooth functionality?

I get tons of those messages:

This is odd. However, it's entirely related to the NICs *Bluetooth*
function, which lives on USB.

What's confusing me is that this device is connected through pcie,
not usb. When i use lspci i get:
[root@alarm log]# lspci
00:02.0 PCI bridge: Marvell Technology Group Ltd. Device 6828 (rev
04)
00:03.0 PCI bridge: Marvell Technology Group Ltd. Device 6828 (rev
04)
02:00.0 Network controller: Qualcomm Atheros QCA986x/988x 802.11ac
Wireless Network Adapter (rev ff)

So the other card is seen as pci device, but the intel is not. I am
really lost now.
The NICs *WiFi* function should be a PCIe device, but the USB
connect/disconnect cycles suggest that there's something wrong with the
electrical connection, which presumably causes the PCIe part of the
device to never appear on the bus.
