Ye, I would recommend rebinding game keys to something you can find while blind, on the edge of keyboard and using additional mouse keys.
All the solutions to press keyboard while in vr require you to have hmd camera or webcam pointing to keyboard along with any free or paid vr overlay apps. Its a hassle to set up and you would eventually decide to use it blind rather than setting it all up each playthrough.
Setup is straightforward, just a hassle with all the steps:
1. find free vr overlay on github
2. run steamvr, run overlay,
3. point webcam to keyboard and output webcam feed to a window
4. attach overlay window to playspace or hmd, done
If you are on quest 2 (like everyone these days), there were some kind of advertised features to peek your keyboard or maybe a button to see hmd camera feeds that you can use to peek, but I dont have one to say more precise, since you are streaming PC game you can basically use same steps but most of overlays are meant for steamv, maybe there are some for oculus.
