Can you disable a VPN VNet gateway service on Azure when you don't need it?

Getting conflicting info from our cloud provider (who I no longer trust to assist because they don't know what they're doing) and forum posts about the same question on Microsoft and I don't know what to believe.

I can't experiment, because it'll probably cost the company money and I can't do shit without getting permission and submitting some kind of business case for things that will potentially cost money.
