VR is sort of a premium format and most players on Itch are looking for free or cheap indie games IMO.
Your best bet is, as has already been mentioned, to focus on announcements elsewhere and direct people back to your Itch.IO page.
The creation of relevant, targeted announcements across various social media platforms outside the Itch.IO community has been going pretty well for me, I am drawing in 20-50 views across my profile daily lately, and that is not considering what is about to happen when my next sale starts in roughly 3 hours. From April 10-12, 2020, I will be dropping my prices pretty dramatically.
