GCP vm disk loss requires server in terminated state

[pawanphalak]

While trying out the GCP VM disk loss experiment(https://litmuschaos.github.io/litmus/experiments/categories/gcp/gcp-vm-disk-loss/). It requires the server to be in terminated state so the test can be completed, I get following error while executing this test

time="2022-08-01T09:24:38Z" level=info msg="[Chaos]: Detaching the disk volume from the instance"
time="2022-08-01T09:24:38Z" level=error msg="Chaos injection failed, err: disk detachment failed, err: googleapi: Error 400: Invalid resource usage: 'To detach the boot disk, the instance must be in TERMINATED state.'., invalidResourceUsage"

Is there a way to force detach the disk from the server while the server is still in running state? We want to test this experiment on a GKE node and we cant stop the node of the GKE nodepool to execute this experiment.
