I assume you want the ideas to still be visible to members of that idea portal but would like to disable the actual voting for a private or public portal? If this is true, can you provide more detail on the use case you have in mind for showing the ideas but not allowing people to vote on them? This will be helpful for understanding the actual requirement and/or problem that you are looking to solve with this change.
Also, is it the desire to disable at the Portal level (i.e. applies to all users) or disable by user, or other?
I would like to disable it for the entire portal. The use case is that I'm using a portal for an FAQ, and don't need voting for questions/answers.
The use case you bring up is a unique one - in using the idea portals as a FAQ.
That said, the prime use of the idea portal is to be a place to capture feedback from stakeholders to help you better understand what your users are looking for. With this in mind, the voting functionality is a key component of the feature that we do not have plans to add a disable setting.
We are planning to use the ideas portal as our common intake. I would not want the end users submitting requests getting concerned if there are no votes for their submitted efforts.
You won't be notified about changes to this idea.
