Hey,
Well firstly, to ignore movement input, in your player controller or your pawn, try these nodes in image below, I use them on my VR character.
As for a full A-Z to set up a VR character, that’s a bit big in scope to answer here. I would recommend checking youtube for VR tutorials in Unreal. There’s plenty around. Also if you make a new project and choose VR Template on the project creation screen, it will give you a fully build VR system ready to go. You can take a look at how it works and adapt it for your needs if you like, you can absolutely use those templates as a base for your project. The VR template is a little complex compared to some of the others, but VR is a bit more of a complex system.
I highly recommend [this link too to Epics base page for VR][2]. They provide a tonne of useful information for setting up any platform of VR
