Hi Emile,
Yes you can, first delete then use ‘commit no-networking’.
However the second statement is not correct. If you do the above and remove the devices and add them again, and add the services back, then the config on the devices will not have the correct refcounts to the existing services, so you will have an impact, for example if then you really want to remove the service later, NSO will not remove any config, because the service when you added it back will have not created any new config having found the service config already present on the device.
Its better if they pose the question differently. What at a high level are they trying to achieve? Why do they think removing/adding devices will help?
You mention that you are repeating here a question from your customer. For customers its good to have them open a TAC case, or have them ask on devnet. So you are not sitting in the middle of a conversation, and also because this list is best effort.
