Prompt user to connect VR Headset

I’m making a project where the game should be able to detect if a VR headset is connected or not and prompt the user to connect one. I easily did this using the “Default” on the Motion Controller Pawn, “Switch On Name” function.

But here is where it gets tricky, I need a regular menu in order to do this, since I can’t run the VR Preview, if no headset is connected. And the problem with a regular menu is that it doesn’t run in VR preview.
I’ve been trying to see if I can switch from Simulate Mode to VR Preview Mode mid game but I’ve been unsuccessful so far.

Why do I need to do this?
I’m a computer engineer student and I added this functionality to the project’s design in order to bump the cyclomatic complexity of my project but I never expected it to be so much of a headache. And I have to find a solution to this problem, so I can’t really ditch it.

So any possible solutions or workarounds to this endeavor?
