Looks like the PCI card variant has been supported for a while:
[/usr/src/linux-next] git blame drivers/net/wireless/realtek/rtlwifi/pci.c | grep RTL8822BE
e298be2a97fda drivers/net/wireless/realtek/rtlwifi/pci.c (Ping-Ke Shih              2017-12-09 11:37:08 -0600   48) 	if (rtlhal->hw_type == HARDWARE_TYPE_RTL8822BE) {

[/usr/src/linux-next] git describe e298be2a97fda
v4.15-rc1-238-ge298be2a97fd

https://linux-hardware.org/index.php?id=usb:0bda-b023  says
the USB flavor is supported by drivers/bluetooth/btusb.c
with config symbols CONFIG_BT CONFIG_BT_HCIBTUSB/

There's an apparently abandoned github driver: https://github.com/lwfinger/rtl8723au_bt
that hasn't been touched in 7 years, and has a Readme that says:

> In this document, we introduce how to support rtk 8723AE/AU BT driver in Linux system.
> Support kernel version 2.6.32~3.13.0

So for us to help you, you're going to have to be a *lot* more detailed about
what kernel release you're using, what the USB/PCI/whatever device you're
working with, and where you got the driver you're trying to get working.
