no worries.. since I didn't get any answer earlier, i had tried the PM APIs (I should have thought of them earlier) and they seem to work as expected.. thank you for confirming..

Hi, apologies for the late reply, we are always low on staff during July, so slower response times are expected.

You should be able to add CONFIG_PM_DEVICE=y to your prj.conf and then call the power management api to suspend and resume the i2c:

pm_device_action_run(i2c0, PM_DEVICE_ACTION_SUSPEND);

pm_device_action_run(i2c0, PM_DEVICE_ACTION_RESUME);

Here's some documentation on managing device power during runtime: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/zephyr/guides/pm/device_runtime.html
