I have never a seen a Bluetooth adaptor without the capability. Currently this laptop has an "Intel Dual Band Wireless-AC 8265" device which reports it can store 16 keys in the NVRAM. I have used the btkey(1) program on NetBSD to read and write keys, but it is basically speaking directly directly to the adaptor so should be possible under any OS where that is possible.
