Can I user PSVR2 without the controllers on PC?

edit: oops, title.

I recently grabbed the PSVR2 PC adapter, and to say I'm disappointed would be an understatement.

I bought the recommended Bluetooth adapter (ASUS BT500) and have the headset less than 3 feet from it, but the controller connections will constantly jump around or drop out.

I bought the adapter for sim-racing, and I don't really need the controllers. Is it possible to boot into the game with a traditional gamepad or mouse instead?
