Hi,
No it is a fixed interval at this time which is part of the status check on the build completion.
You can change the interval the check is performed in the Constants.pm file, it is VM_CHECK_INTERVAL and is set to 10 seconds if you do though you may need to adjust the vadk:boot and vadk:hang attributes of the ProvisioningTimeouts section in your build profile since they are divided by that interval in order to set a max limit.
