You have to decide which method you prefer to use. You can't use both as any change you do locally will be overwritten by ObiTalk.
To do configuration locally go to:
System Management > Auto Provisioning > Auto Firmware Update > Method: Disabled
System Management > Auto Provisioning > ITSP Provisioning > Method: Disabled
System Management > Auto Provisioning > ObiTalk Provisioning > Method: Disabled
