kernel needs CONFIG_BT_HCIVHCI

I found the kernel config file and this variable is set as "is not set" what do I do?

[mlehtima]

You set it to CONFIG_BT_HCIVHCI=y in your device's kernel defconfig file and rebuild the kernel

if I change it in this file and restart the phone, will it change?

[krnlyng]

Unfortunately no, you will need to recompile the kernel and flash it.

Where do I get the source and how do I compile it? (Android 12)
