Unfortunately, using Ubuntu core is a requirement.
Linux localhost.localdomain 4.4.0-1087-snapdragon #92-Ubuntu SMP Tue Feb 13 10:27:47 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux
Is there a way to check which process is running wpa_supplicant?
As you referred the network manager snap on the end of your response,
I was initially trying to use the wifi-ap snap to configure a AP on the dragon board.
