STM32WB - can I provision mesh netkey, appkey, unicast address etc without using a BLE connection to do this.

I would like to provision mesh nodes with the netkey, appkey, unicast address etc via UART or I2C. However I don't find an API function call to the mesh library to allow this. All I see are

MOBLE_RESULT BLEMesh_InitUnprovisionedNode(void);

MOBLE_RESULT BLEMesh_InitProvisionedNode(void);

MOBLEBOOL BLEMesh_IsUnprovisioned(void);

MOBLE_RESULT BLEMesh_Unprovision(void);

but nothing to do the actual provisioning. Thanks
